Abstract :
We present a Ka-band grid amplifier power module. The module is fully packaged with waveguide input and output flanges. It includes a driver grid amplifier chip for gain, followed by a booster grid amplifier chip for power. With a 50°C baseplate temperature, the module has a small signal gain of 12 dB. The single-chip output booster stage delivers over 16 Watts of saturated power. The module delivers over 10 Watts output with a constant 1.6 Watts input over a 550 MHz bandwidth. We also present a large-signal third-order intermodulation and AM/PM conversion measurements, which are consistent with expectations. To our knowledge, this is the highest power ever reported from a monolithic single-chip power amplifier at Ka-band.
