“…The peak gain is 11.7dB with a 1-dB bandwidth'of 470MHz. The gain is consistent with other results using this process: the amplifiers in [3] and [5] both provide 6 dB per stage of amplification. The input and output reflections are better than -7dB over this band and the gain group delay variation was less than 300psec.…”

Abslracf -We present a Ka-band Grid Amplifier power module. The module is fully packaged with wavegnide input and output flanges. It includes a driver Grid Ampllder chip for gain, followed by a booster Grid Amplifier chip for power. With n 50°C baseplate temperature, the module has a smallsignal gain of 12dB. The single-chip output booster stage delivers over 16 Watts of saturated power. The module dellven over 10 Watts output with a constant 1.6 Warts input over a 550-MBz bandwidth. We also present large4signal third-order intermodulation and A M M conversion measurements, which are consistent with expectations. To our knowledge, this is the highest power ever reported from a monolithic singlechip power ampliner at ffi-band.Index Terms -Power combiners, millimeter wave power amplifiers.

W O Ka-band power amplifier MMICs, 4W and 6W, with high power density and gain are presented. Each amplifier was designed using a 5-stage topology to demonstrate over 30dB of gain. The 4W design exhibited a peak saturated output power of 37.2dBm and a chip output power density of 532mWmm'. This is the highest recorded power density for a Ka-band power amplifier design to date.The high gain and power density of these designs make them ideal for low-cost Ka-band transmit systems.
