Custom MMIC Adds Three New GaN LNAs
New low noise amplifiers have output IP3 of +32 dBm and input power handling of 5W
Custom MMIC, a US developer of monolithic microwave integrated circuits (MMICs), has added to its GaAs and GaN MMIC portfolio with three new low noise amplifiers (LNAs) and evaluation boards.
The CMD276C4, CMD277C4 and CMD278C4 GaN MMIC LNAs are said to deliver high linearity performance with output 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.
These new MMIC LNAs are housed in a leadless 4x4 mm QFN package. They are 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.
