The PMA4-9163+ is a GaAs MMIC multi-stage medium power driver amplifier operating from 9 to 16 GHz. The amplifier provides 23.5 dB of linear gain, greater than 0.2 W of saturated output power with 28% power-added efficiency, +52 dBm OIP2, and +30.6 dBm OIP3 at 12 GHz. The device operates on a +5 V supply and consumes 145 mA of quiescent current. The amplifier is 50Ω matched at the input and output, making it easy to implement and comes in an industry standard 4×4 mm 24- lead QFN-Style package for ease of integration into dense circuit board layouts.
