Breakthrough GaAs and GaN MMICs Being Rolled out by Custom MMIC at IMS 2018

Chelmsford, MA – June 07, 2018 – Custom MMIC (, a leading developer of performance driven monolithic microwave integrated circuits (MMICs), is excited to be exhibiting in a new booth at the 2018 International Microwave Symposium (IMS) in Philadelphia, PA, June 12th through 14th. They’ll be in Booth #851 and discussing exciting new GaN and GaAs MMIC technology breakthroughs.

Released here for the first time, Custom MMIC has broken the noise barrier in MMIC form with their industry-first Ultra Low Noise Amplifier (ULNA) MMIC. The CMD283C3 provides an incredible 0.6 dB noise figure, outperforming all other LNA MMICs, and rivalling discrete component implementations. It operates over a frequency range of 2 GHz to 6 GHz (S & C-band) and has output IP3 of +26 dBm.

Four members of a new GaAs MMIC digital attenuator family are also being introduced. The CMD279 and CMD280 operate up to 30 GHz with 5-bit control. Attenuation range is up to 15.5 dB. Two, 2-bit attenuators, the DC-35 GHz CMD281 and DC-40 GHz CMD282, offer coarser control in 2 and 4 dB steps respectively. All four devices offer input IP3 of +42 dBm.

Their latest Distributed Amplifier, the DC-20 GHz CMD249P5, offers a positive gain slope with nominal 12 dB gain. The GaAs device features output Psat of +30 dBm and output IP3 of +38 dBm.

Custom MMIC also continues to enhance their line of unique low phase noise amplifiers (LPNAs) as well. Responding to customer requests to assist in reducing unwanted phase noise and improve signal integrity and target acquisition in military radar systems, these LPNAs operate up to 40 GHz and offer low phase noise performance down to -165 dBc/Hz at 10 kHz offset. They serve as Local Oscillator (LO) drivers or receiver amplifiers in a variety of phased array radar, EW, military radio, instrumentation, and aerospace and space communication designs.

MMICs on the horizon from Custom MMIC include more ultra-low noise amplifiers and digital attenuators, as well as broadband distributed power amplifiers and GaN mixers. All these new MMICs are also being added to their “space-qualifiable” list.
