Abstract :
A W-band DHBT power amplifier chip set consisting of a cascode power amplifier and a driver amplifier fabricated in InP technology is reported. The cascode power amplifier has a total of 160 um2 of emitter area and results in a power gain of 8.5 dB and saturated output power of more than 14.4 dBm at 94.5 GHz. The driver power amplifier provides a peak signal gain of 9.8 dB at 102 GHz and peak saturated output power of 9.5 dBm at 94.7 GHz. To the author´s knowledge, this is the highest reported output power and gain above 90 GHz for an HBT amplifier.
