Marki Microwave introduces an ultra-efficient broadband MMIC multiplier available in two unique drive level options. The MMD-2060L/H doubler spans an impressive 20 to 60 GHz of output bandwidth, features very low conversion loss and provides superior suppression with a typical 37dBc fundamental and 40dBc 3F suppression value. Based on your power requirements select either the MMD-2060L, which provides -6 dBm output power with a nominal +5dBm drive, or the MMD-2060H, which provides 0 dBm with +11dBm input. Ideal for a wide range of SATCOM, radar, 5G, and point-to-point applications, the MMD-2060L/H is available now in bare die or connectorized modules.

MQS-0218: Excellent Phase Balance from 2-18 GHz

MMIQ-0626HSM

Introducing the first triple-balanced surface mount MMIC mixer that covers X/Ku/K bands in a small QFN package. The high linearity MM2-0530HSM features massive overlapping bands with RF/LO from 5 to 30 GHz and IF from 2 to 20 GHz. The unique design provides IP3 of +28dBm and optimal spurious suppression, especially for difficult IF harmonics. Port-to-port isolations are an exceptional 35dB typical.

For lower LO drive applications we offer the MM2-0530LSM.  Both are available in 5 x 5 mm QFN, on an eval board, as bare die, or in a high performance connectorized module.

Our popular MMIC equalizer die are now offered in surface-mount 3mm x 3mm QFN packages. Optimized for excellent return loss over the entire band, the MEQ series equalizers provide consistent unit-to-unit performance in a small low-cost form factor. The MEQX-7ASM family is available in four configurations and provide positive slope from DC to 7GHz with DC attenuation options between 3 and 12dB. Coming soon are the DC-14GHz MEQX-14ASM and DC-20GHz MEQX-20ASM families of equalizers. S-parameters are available on our website.

Marki Microwave is proud to launch their first series of GaAs MMIC quadrature hybrid couplers spanning 9 GHz to 42 GHz. Each 90 degree hybrid coupler was optimized for high isolation and offers exceptional amplitude and phase balance. Three products are available at launch: MQH-0920 (9 to 20 GHz), MQH-1434 (14 to 34 GHz), and MQH-1842 (18 to 42 GHz). Applications include single sideband upconverters, image rejection downconverters, IQ modulators, balanced amplifiers, microwave correlators, and microwave Butler matrices. All MQH’s are available as wire-bondable die.

Marki Microwave continues to be the leader in broadband balun design with their latest multi-octave GaAs MMIC balun. The MBAL-1440 provides outstanding amplitude and phase balance over a range of 14 to 40 GHz.  Offering high isolation and common-mode rejection, this balun is ideal for high-speed track-and-hold amplifiers for ADCs, balanced amplifiers, and signal integrity applications. MBAL-1440 is available as wire-bondable die.

Marki Microwave is introducing the latest addition to our world-leading GaAs MMIC IQ Mixer family with the MMIQ-4067LU module. This V-band mixer spans 40 to 67 GHz with an IF bandwidth of DC to 20 GHz. Due to the excellent phase and amplitude balance of its on-chip LO quadrature hybrid, the MMIQ-4067LU rovides an exceptional 33dB of LO-RF isolation and 35dB of image rejection.  It is available today in a connectorized module.

At Marki Microwave our mission is to empower engineers to shatter performance barriers. True to that mission, we offer a wide selection of high linearity, wide bandwidth GaAs MMIC IQ mixers for applications in image reject mixing, vector amplitude modulation, band shifting, and IQ modulation/demodulation. Our RF, LO, and IF bandwidths are the widest in the industry, enabling engineers to push the boundaries of what is possible. Just as with our double and triple balanced mixers, we typically offer our IQ mixers in two diode options to allow customization for either low LO drive or high linearity applications. When performance matters, there’s only one name in mixers – Marki Microwave.

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.

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.
