Custom MMIC has released three new unique GaN low noise amplifiers (LNAs) with easy to use evaluation boards.
The new GaN MMIC LNAs, CMD276C4, CMD277C4and CMD278C4 deliver high linearity performance with output IP3 of +32 dBm while offering high input power handling capabilities of up to 5W. The high input power handling feature enables system designers to avoid limiters and other protection networks, while still achieving an extremely low noise figure over the operating bandwidth. The MMIC LNAs are housed in a leadless 4×4 mm QFN package. They are ideally suited for radar and electronic warfare (EW) applications where high performance and high input power survivability are required.
The CMD276C4 is a 2.6 to 4 GHz (S Band) LNA delivering greater than 14 dB of gain with a corresponding output 1 dB compression point of +25.5 dBm and a noise figure of 1.2 dB.
The CMD277C4 is a 5 to 7 GHz (C Band) LNA with 20 dB of gain, output 1 dB compression point of +26.5 dBm and a noise figure of 1.2 dB.
The CMD278C4 is a broadband 8-12 GHz (X Band) LNA with 15 dB of gain, output 1 dB compression point of +28 dBm and a noise figure of 1.8 dB.
