Development of Ka/Q-band 100 W peak power MMPM

Abstract

We are currently developing a Ka/Q-band 100 W peak power MMPM which is suited to millimeter-wave FWA base stations or satellite terminals. The innovative power-saved MMPM has the feature of a peak RF output power of more than 100 W (100 W peak) with power consumption of approximately 100 W at an actual operating output power level of 10 W cw. The TWT is designed so as to reduce power consumption by adopting a four-stage-depressed collector and setting the collector voltages matched to the actual operating condition (output power of 10 W cw). In addition, we have researched several kinds of basic technology, for example, for RF loss reduction and secondary emission suppression.
