Abstract :
This paper reports the first high-power GaN MMIC covering 70 percent of W-band (75-110 GHz). Using an on-chip traveling-wave power combiner circuit, it achieves power levels of greater than 1 W CW over the 80 to 100 GHz band and a peak power of 2 W CW at 84 GHz. Operating in a pulsed mode (10% duty), this MMIC produces a peak power of 3.2 W at 86 GHz. This work represents the first application of an on-chip combining network to simultaneously achieve high power levels and wide bandwidths at W-band frequencies.
