Monolithic microwave integrated circuit developer Custom MMIC of Westford, MA, USA says that its new CMD276C4, CMD277C4 and CMD278C4 gallium nitride (GaN) MMIC low-noise amplifiers (LNAs) deliver high-linearity performance with output third-order intercept point (IP3) of +32dBm while offering high input power handling of 5W.
The high input power handling feature enables system designers to avoid limiters and other protection networks, while still achieving extremely low noise figure over the operating bandwidth.
The CMD276C4 is a 2.6-4GHz (S-band) LNA delivering greater than 14dB of gain with a corresponding P1dB (output power at 1dB compression point) of +25.5dBm and a noise figure of 1.2dB.
The CMD277C4 is a 5-7GHz (C-band) LNA with 20dB of gain, P1dB of +26.5dBm and a noise figure of 1.2 dB.
The CMD278C4 is a broadband 8-12GHz (X-band) LNA with 15dB of gain, P1dB of +28dBm and a noise figure of 1.8dB.
Housed in a leadless 4mm x 4mm QFN package, the new MMIC LNAs are suited to radar and electronic warfare (EW) applications where high performance and high input power survivability are required.
