New 20 to 50GHz LO Amplifier
Provides High Gain in SMT Package
Marki Microwave introduces the AMM-6702SM, the industry’s first high gain LO driver amplifier to provide a wide 20 to 50GHz bandwidth in a convenient surface mount package. High linearity broadband mmwave mixers such as our MM1-1850HSM require high power broadband LO driver amplifiers. This GaAs MMIC amplifier provides over 24 dB gain and over +19 dBm saturated output power in a power-efficient design that is capable of driving Marki surface mount S-diode mixers. The  AMM-6702SM‘s unmatched combination of bandwidth, power and efficiency make this an ideal LO driver amp for SATCOM, radar, 5G, and point-to-point applications.

New Low Phase Noise 2-29GHz
LO Amplifier Optimized for Marki Mixers

Phase noise is a critical concern in applications ranging from sensitive military radars to state-of-the-art wireless chipset testing to ultra low-noise frequency source design. For this reason, Marki Microwave is proud to introduce the APM-6848, our first low phase noise amplifier! Featuring positive-only bias and requiring no external bias tees or power sequencing, this GaAs HBT MMIC LO driver will produce more gain and more output power up to higher frequencies than any competing GaAs HBT amplifiers on the market.  The APM-6848 is unique among wideband GaAs HBT amplifiers in that it can provide a +21dBm typical saturated output power with an input power of only 0 to 5dBm.  This is ideal for driving our L, H, and S-diode mixers in a single stage from your VCO or synthesizer output. Careful consideration was made to power consumption, drawing only 47mA and providing 23dB of gain, making it one of the most power efficient wideband low phase noise amplifiers on the market. The APM-6848 is available today in bare die and connectorized module, and the surface-mount version is coming soon (contact us to learn more).

The HLM-40 is a multi-stage GaAs Schottky diode limiter designed to protect sensitive RF components in high power conditions while maintaining high linearity during small-signal operation. The wide 40GHz bandwidth and 20W peak power handling makes the HLM-40 suitable for pulsed radar, electronic warfare, 5G and more. During the design phase, special attention was paid to linearity: a typical P1dB of +15dBm at 10GHz was achieved while providing flat leakage of +18dBm. By utilizing Schottky diodes rather than PIN diodes recovery time is expected to be improved. HLM-40 is available now as bare die and connectorized module.

The DLM-10SM is a tunable, dual channel GaAs Schottky diode signal limiter featuring excellent IP3, insertion loss, and return loss. The limiting level is adjustable with an off-chip bias network, and the two channels can be used for differential or single-ended signals. Typical input P1dB is +10dBm with an operating range of DC to 10 GHz. The DLM-10SM is available in a lead-free, RoHS compliant 3×3 mm QFN surface mount package.

We’re blessed to have a legion of die-hard mixer customers always asking us to shatter performance barriers! Last month it was our +40dBm IIP3 MT3-0113SCQG, and now we’re proud to introduce the 2-22 GHz MM1-0222H mixer with a 10:1 bandwidth ratio covering critical bands for electronic warfare, radar, and communication applications. This high IP3, high isolation MMIC mixer operates with a wide LO drive of +11 to +20dBm and has a low 6dB conversion loss through C-band. The MM1-0222H is available as bare die and connectorized module.

At Marki Microwave, we’re known for pushing the limits on instantaneous bandwidth and it doesn’t get much harder than doing this in an IQ mixer. Building on the accomplishment of the 2 to 18 GHz quadrature splitter MQS-0218, the MMIQ-0218L has an impressive 2 to 18 GHz RF/LO bandwidth and DC to 3 GHz IF. To achieve this 9:1 BW ratio required the expert design and integration of ultrawide mixers, quad hybrids, and power dividers. This MMIC IQ mixer provides +5dBm Input P1dB, 27 dB of image rejection, and 58 dB of L-R Isolation with an LO of +17dBm. Our MMIQ series mixers are used in a variety of applications to provide vector modulation, band shifting, and up/downconversion for radar, EW, test & measurement, and quantum computing. The MMIQ-0218L is available today in bare die and connectorized module.

The RF/LO bandwidth is 1.5 to 13 GHz and the IF is a wide 10 MHz to 7 GHz. For evaluation and prototyping we recommend pairing the connectorized EVAL-MT3-0113S evaluation module with the new ADM3-0022PA 1-Watt amplifier.

 

Our new broadband ADM3-0022PA power amplifier produces 1 Watt of saturated output power from a +0 dBm input thanks to a 3-stage design providing 35 dB of small signal gain. Featuring built-in gain equalization, the ADM3-0022PA offers exceptionally flat frequency response from DC to 22 GHz in both linear and saturated modes. It’s an ideal LO driver amplifier for Marki T3 and MT3 high linearity mixers. The ADM3-0022PA is available with or without a heatsink and is intended for lab use.

Our  T3 mixers is the most advanced mixer circuit available in the world. In addition to broadband overlapping LO, RF, and IF bands, it has the potential for extremely high linearity. T3 mixers are built in both hybrid and MMIC form. The hybrid construction allows for ultra-broadband coverage on all three ports (RF,LO, and IF), whereas the MMIC MT3 series offers the scalability and repeatability of a MMIC with the linear performance of the T3.  Click here for our full lineup of bare die, surface mount, and connectorized T3 mixers up to 40 GHz.
 
The T3 mixer is a true-commutating mixer. This means it will provide increasing two-tone intermodulation suppression, input 1-dB compression, and spurious suppression (for most spurs) as the rise time of the LO signal is increased by either increasing sine wave LO drive or, for optimal results, using a square wave LO. The ADM series amplifiers were designed to provide strong odd (3rd and 5th) harmonics and are an ideal choice as a square wave LO generator for the T3 mixers.
 
The Two-Tone-Terminator (T3) mixer is the most sophisticated mixer circuit on the market today and offers unparalleled performance when compared to all other mixer technologies.

The MFB-5350 bandpass filter is the latest addition to Marki Microwave’s growing catalog of in-stock MMIC filters. This V-band filter has a passband of 37 to 70 GHz with a low 1.2 dB insertion loss and excellent return loss. Our GaAs MMIC process ensures highly repeatable performance and scalability for high volume applications as pre-select, image, or LO cleanup filters. The MFB-5350 is available today in wire-bondable die.

Marki is proud to introduce surface-mount versions of our low-barrier diode MMIC IQ mixers. The MMIQ-0520LSM and MMIQ-0626LSM, with wide RF/LO bandwidths of 5 to 20 GHz and 6 to 26 GHz respectively, provide exceptional LO-RF isolation and spurious suppression. When used as an image reject or a single-sideband mixer (with an external IF hybrid) these IQ mixers provide excellent image/sideband suppression. A low +3dBm drive level is all that’s required. MMIQ-0520LSM & MMIQ-0626LSM are available in 4×4 mm QFN or connectorized evaluation module.

Introducing a broadband high-linearity mixer optimized for the emerging 5G market. Whether designing for 28 GHz, 39 GHz, or one of several proposed bands this one mixer answers the call with ultra-wide RF/LO bandwidth covering 10 to 44 GHz and IF bandwidth of DC to 14 GHz. Like all Marki mixers, the MM1-1044L/H features outstanding spurious suppression and isolations. This mixer is offered in two diode options for tailoring to your specific LO drive level and linearity requirements. Unique to the MM1-1044L/H, and attractive for high volume 5G applications, is that this performance is offered in a smaller form factor and at a fraction of the cost of other high performance Marki mixers in this frequency range.
Available now as 0.8 mm x 1.2 mm wire-bondable die or in a connectorized module.

Introducing Marki Microwave’s latest passive frequency doubler, the MMD-3580L, is designed specifically for V-band applications with output frequencies from 35 to 80 GHz. Featuring a low 11 dB conversion loss, the MMD-3580L provides superior suppression with a typical 38 dBc fundamental and 44 dBc 3F suppression value. A unique feature is the low input power requirement of +7dBm, ideal for high frequency applications where power comes at a premium.
This doubler is available as bare die or in one of two connectorized modules.
MMD-3580LCH: Bare die operates with 35-80 GHz output
MMD-3580LU-KW: Module with 35-80 GHz output (1mm output connector)
MMD-3567LU: Module with 35-67 GHz output (1.85mm output connector)

Marki Microwave now offers a versatile DC to 35 GHz amplifier in a bare die package, with 14 dB of gain and +22 dBm saturated output power. The ADM-5974CH provides efficient optimized LO drive to all Marki Microwave mixers, ideal for electronic warfare, clock distribution, or test and measurement applications. The design allows for single-supply DC biasing for customer convenience or for optional negative bias to increase even harmonic rejection and decrease DC current consumption. ADM-5974CH is built with a low-noise GaAs pHEMT process to provide competitive phase noise performance.
The ADM-5931CH offers an efficient low-power solution for use as a pre-amp or LO driver amplifier, providing 11 dB of gain and +17 dBm saturated output power with less than 100 mA of DC bias current. ADM-5931CH‘s extended DC to 28 GHz gain and low even harmonic generation provide enhanced linearity as an LO driver for Marki Microwave’s T3 mixers. Requiring only a single positive bias voltage, a negative supply voltage can be added for enhanced even harmonic rejection and reduced DC current draw. Low-noise pHEMT technology gives the ADM-5931CH competitive phase-noise performance. ADM-5931CH is available as bare die.
MMIC filters from Marki Microwave provide outstanding savings in board space and cost, while offering exceptional in-band performance and out-of-band rejection. We’re introducing three new filters for K and Ka band applications. MFB-2400 has a bandwidth of 21 to 27 GHz, MFB-2500 covers 18 to 32 GHz, and MFB-3450 targets both K and Ka band with a 24 to 45 GHz bandwidth. All three filters feature a low 1.5 dB insertion loss, excellent 15 dB return loss, and 30 dB ultimate rejection.
 These filters are tiny at only 1.25 mm2. With their small footprint and low insertion loss, these filters can easily be inserted as pre-select or image reject filters at RF front-ends or as clean up filters in clock paths. Our MMIC process ensures highly repeatable performance and scalability for high volume applications. MFB-2400MFB-2500, and MFB-3450 are available today in wire-bondable die.

Marki Microwave is introducing 3 new passive GaAs MMIC mixers, each covering RF/LO from 2 to 12 GHz and IF DC to 3 GHz. These broadband mixers are of similar design offering exceptional port-to-port isolations with LO-IF approaching 50dBc.

What differentiates each mixer is the LO drive required and the resultant linearity. The MM1-0212L will operate with as low as +1dBm LO drive and provide IIP3 up to +14dBm at nominal drive levels of +9dBm. The MM1-0212H has a nominal LO drive of +15dBm with IIP3 of +23dBm. For the most demanding applications we offer the MM1-0212S with nominal LO drive of +20dBm (up to +23dBm) and an outstanding IIP3 of +29dBm.
