GaAs PHEMT MMIC 1 WATT POWER AMPLIFIER, DC - 22 GHz
The hmC797A is a GaAs mmiC phemT Distributed power Amplifier die which operates between DC and 22 Ghz. The amplifier provides 14.5 dB of gain, 40 dBm output ip3 and +28 dBm of output power at 1 dB gain compression while requiring 400mA from a +10V supply. This versatile pA exhibits a positive gain slope from 3 to 21 Ghz making it ideal for ew, eCm, radar and test equipment applications. The hmC797A amplifier i/os are internally matched to 50 ohms facilitating integration into mutli-Chipmodules (mCms). All data is taken with the chip connected via two 0.025mm (1 mil) wire bonds of minimal length 0.31 mm (12 mils).
