Abstract :
A push-pull power MMIC operating over the 24 to 38 GHz band is presented. Employing a CPW circuit medium, this IC has demonstrated an output power of 0.46 watt with a power-added efficiency of 26% at 25 GHz. The associated power gain was 14.6 dB. The size of this chip is a very compact 1.5/spl times/2.55 mm/sup 2/.
