Custom MMIC continues to expand its extensive GaAs and GaN MMIC portfolio. Three new unique GaN low noise amplifiers (LNA) are now fully released and offered with easy-to-use evaluation boards. They are well suited for radar and electronic warfare (EW) applications, where low noise figure and high input power survivability are required.

In addition to low noise figure, the CMD276C4, CMD277C4 and CMD278C4 GaN MMIC LNAs deliver high linearity with output IP3 of +32 dBm, while offering high input power handling of 5 W. The high input power handling feature enables system designers to avoid limiters and other protection networks, while achieving extremely low noise figure over the operating bandwidth.

LNA Performance Summary

The CMD276C4 is a 2.6 to 4 GHz (S-Band) LNA has a noise figure of 1.2 dB, with greater than 14 dB gain and a 1 dB compression point of +25.5 dBm.

The CMD277C4 covers 5 to 7 GHz (C-Band), with 1.2 dB noise figure, 20 dB gain and 1 dB compression point of +26.5 dBm.

The CMD278C4 is a broadband 8 to 12 GHz (X-Band) LNA with a noise figure of 1.8 dB, 15 dB gain and 1 dB compression point of +28 dBm.

These new MMIC LNAs are housed in leadless 4 mm x 4 mm QFN packages.
