Abstract :
A state-of-the-art 35-GHz monolithic GaAs power amplifier, based on metal semiconductor field-effect transistor (MESFET) technology, is developed for millimeter-wave communications and seeker applications. Both single-ended and balanced amplifier configurations, with on-chip DC-block and bias networks, are designed and evaluated. A cascaded four-stage amplifier exhibited 14.6 dB of linear gain and 300 mW of saturated output power at 35 GHz. These MMIC chips are very flexible and can easily be combined/cascaded to achieve even higher gains and greater output power using low-loss off-chip power combiner/dividers. These amplifiers are suitable for future military millimeter-wave systems applications
