A compact PA MMIC module for K-band high-speed wireless systems

A K-band high-power MMIC amplifier module in a low-cost metal-ceramic package has been developed to provide an easy insertion of PA MMICs into K-band high-speed wireless systems. This PA module is comprised of a driver amplifier MMIC and a power amplifier MMIC with a total gain of 30 dB and a P/sub 1 dB/ of 33.5 dBm at frequencies between 23 and 26 GHz. The total performance of this module, G(dB)/spl times//spl Delta/f/f/sub 0/ is two times higher than previously reported works.
