A Novel Reconfigurable GaN Based Fully Solid-State Microwave Power Module for Communications/Radar Applications

[摘要] The paper presents the design, integration, and performance of a novel S-/X-band, GaN based, fully solid-state microwave power module (SSMPM). The SSMPM includes diplexers, pre-amplifiers, a multi-stage medium power amplifier, SPDT switches, and CW/Pulsed high-power amplifiers. These components are synergistically integrated such that a single SSMPM is capable of being dynamically reconfigured to function as a S-/X-band amplifier for TT&C/telecommunications for command/science date downlink and radar for remote sensing onboard a planetary exploration spacecraft. The SSMPM is capable of delivering Psat of 39.5 dBm (~10 W CW) at S-band, Psat of 46.7 dBm (~45 W CW) at X-band, and Psat of 51.2 dBm (~122 W Pulsed) at X-band.
