Abstract :
A 220 GHz solid state power amplifier MMIC is presented demonstrating 58.4 mW of output power with 5.4dB compressed gain. The 8-cell amplifier has a small signal gain of 8.9 dB at 220 GHz, and 3-dB bandwidth from 206 to 242GHz. Amplifier cells are formed using a 250nm InP HBT technology and a 5um BCB thin-film, non-inverted microstrip wiring environment. Power division and combining of the eight amplifier cells is done by a 2-1 quarter wave combiner series connected to a 4-1 Dolph-Chebyshev combiner. More than 50mW of output power was observed from 215 to 225GHz.
