The AMM-6702UC5 is a connectorized millimeter wave amplifier with an ultrawide 20 to 55 GHz bandwidth, 24 dB gain, and up to +23 dBm saturated output power with only a 0dBm input. To enable wide bandwidth and superior efficiency at mmwave, we designed this amplifier using a depletion-mode pHEMT process which typically requires a negative voltage, positive voltage, and power sequencing. However, we’ve simplified matters and designed a single-supply sequencer board and paired it with our popular AMM-6702UC amplifier, thus creating the new AMM-6702UC5 requiring only a single +5V supply for operation. The AMM-6702UC5‘s unmatched combination of bandwidth, power, and efficiency make this an ideal LO driver amp for SATCOM, radar, 5G, and point-to-point applications and pairs exceptionally well with high linearity mmwave mixers such as our MM1-1850MM1-1467 and MM1-1857.

The MMIQ-0218 is the only 2 to 18 GHz IQ mixer available in the world, enabling architectures for electronic warfare that were otherwise impossible. Building on the accomplishment of the 2 to 18 GHz quadrature splitter MQS-0218, the MMIQ-0218 has an impressive 2 to 18 GHz RF/LO bandwidth and DC to 3 GHz IF. The MMIQ-0218LSM provides +5dBm Input P1dB, 27 dB of image rejection, and 58 dB of L-R Isolation with an LO of +17dBm. Our latest release, the MMIQ-0218HSM, increases input P1dB to +13dBm with an LO of +26dBm. Our MMIQ series mixers provide vector modulation, band shifting, SSB and image-reject mixing, and up/downconversion for applications such as radar, EW, test & measurement, and quantum computing. These MMIC IQ mixers are available in surface mount, bare die, and connectorized modules.

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 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.

Do you have a seemingly impossible linearity spec to meet? Our latest innovation, the MT3-0113SCQG surface-mount mixer, is capable of Input IP3 values up to an astounding 40 dBm. This GaAs MMIC mixer utilizes our proprietary T3 architecture and incorporates the latest design techniques to deliver a high +27dBm input P1dB while also offering excellent spurious suppression. 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.

Sine-wave operation is also supported. RF and LO cover 1.5 to 13 GHz, and the IF is 0.25 to 5 GHz. With 40 dB of port-to-port isolation and over 60 dBc spurious suppression, this latest entry to the T3 product family is ideal for high performance radar, radio and test applications. MT3L-0113HSM is available in a surface-mount QFN or connectorized evaluation module.

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. To learn the theory behind its operation and how this directly translates to improved P1dB, IP3 and spurious performance, download our T3 Primer.
