8-12 GHz (C, X Band)GaN Low Noise Amplifier

The CMD278C4 is a broadband MMIC GaN low noise amplifier housed in a leadless 4x4 mm QFN package. The CMD278C4 is ideally suited for microwave radios and X-band applications where small size and high input power survivability are needed. The broadband device delivers 15 dB of gain with a corresponding output 1 dB compression point of +28 dBm and a noise figure of 1.8 dB. The CMD278C4 features an RF input power survivability of greater than 5 Watts.

Custom MMIC Space Qualified MIMCs
Space Qualification

Custom MMIC strives to design all our MMIC devices in a manner such that they can be readily chosen for your space applications. We offer turnkey space screening / testing service when a device is categorized as "Ready for Space Screening" on our website. In some cases, our devices have already been "Space Qualified" and are often available from stock. Just let us know when requesting price and delivery, or technical support, if your devices will be used in space.
