Abstract :
A Ku-band molecular beam epitaxy (MBE) monolithic power amplifier is reported. In the design, two pairs of monolithic microwave integrated circuits (MMICs) combined in parallel are balanced between Lange couplers and given by a fifth identical MMIC. Each MMIC is a two-stage power amplifier which incorporates a full interstage matching network and a partial input matching network. Individually, the MMICs deliver more than 3 W of power, 11 dB gain, and more than 20% power-added efficiency (PAE) from 15 to 18 GHz. The full power module has 8 W of P/sub out/, 20 dB gain, and 14% PAE at 18 GHz. The module could be tuned for a 1-GHz instantaneous bandwidth anywhere in the 15-18 GHz band.<>
