More Info on Custom MMIC

Helping you optimize your microwave signal chains with the best MMICs in Their Class.

From next-generation long range military radar systems, including phased array and AESA radar, to advanced aerospace and satellite communications, microwave signal chains are being pushed to new limits—and no one understands this more than Custom MMIC. Founded in 2006 as a fabless circuit designer, we’ve been entrusted by government and defense industry OEMs with their biggest microwave circuit challenges.

Today, we are a complete ISO-certified designer and supplier of the best MMICs in their class. We offer a rapidly growing family of high performance RF / microwave MMIC products while still offering the design of unique RF / microwave MMIC solutions as requested. We have longstanding and flexible relationships with world-class MMIC foundries and offer the highest reliability, including military and space qualification.

We’ve recently invested in a new modern engineering, testing and packaging facility, and are happy to be gaining industry recognition as one of the most responsive MMIC vendors by turning around requests for prices, application support, and evaluation boards in a timely manner. Review our high performance "off-the-shelf" MMIC solutions and custom design services and allow us to solve your various size, weight, performance, and cost (SWaP-C) - challenges in your microwave signal chain. We're certain you’ll find our costs and pricing model attractive, too.

Our MMIC Product Line:

Amplifier MMICs
Our amplifier MMIC products provide industry-leading gain flatness and stability, noise figure, phase noise and linearity, and also offer unique benefits such as positive gain slope, positive biasing, and 50 ohm matching. Models include low noise amplifiers (LNAs), driver amplifiers, power amplifiers, low phase noise amplifiers (LPNAs) and broad range distributed amplifiers.

Control Device MMICs
Our switching and frequency conversion MMICs offer state-of-the-art insertion/conversion loss, bandwidth, and isolation for advanced signal chain design. These products include SPST to SP4T Switches, RF Phase Shifters, and Voltage Variable Attenuators.

Mixer and Multiplier MMICs
Our gain and phase control products provide the highest accuracy, along with low loss. Our mixer models include fundamental mixers, dual mixers, and I/Q / I/R mixers. Our RF multiplier MMIC family includes both passive and active solutions.

Space Qualified MMICs
For RF / microwave designs that require complete space qualification, Custom MMIC offers full screening of our standard MMICs to MIL-PRF-38534 Class K & MIL-PRF-38535 Class S. Several low noise amplifiers (LNA) MMICs, and a driver amplifier MMIC, have been previously space qualified.
