The AMMP-6425 MMIC is a broadband 1W power amplifier in a surface mount package designed for use in transmitters that operate in various frequency bands between 18GHz and 28GHz. At 25GHz, it provides 31dBm of output power (P-1dB) and 25dB of small-signal gain from a small easy-to-use device. The device has input and output matching circuitry for use in 50 environments. The AMMP-6425 also integrates a temperature compensated RF power detection circuit that enables power detection of 0.25V/W. DC bias is simple and the device operates on widely available 5V for current supply (negative voltage only needed for Vg). It is fabricated in a PHEMT process for exceptional power and gain performance.
