Abstract :
A 2-stage, push-pull power MMIC operating over the 20 to 36 GHz band is presented. With a P/sub 1dB/ and P/sub SAT/ of 0.51 W and 0.78 W respectively, this IC has demonstrated a 1-dB power bandwidth, at a minimum output power of 28 dBm, that extends from 22 to 31 GHz. This result represents the highest combination of output power and bandwidth reported from a power MMIC operating at K/Ka-band frequencies. The size of this IC with integrated baluns is a compact 1.5 /spl times/ 3.75 mm/sup 2/.
