CMD278C4

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

Qorvo's 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.
