April 7th, 2024 – South Korea successfully launched its first "425 Project" Synthetic Aperture Radar (SAR) Satellite. Onboard the K425 Satellite is Micross' custom TPSUR DC-DC power supply – designed specifically for SAR applications based on the standard TPSU model. The redundant TPSUR power supply consists of two identical power supplies installed in a single mechanical structure, and is internally cross strapped on the output rails. The DC-DC converter supplies both the transmitter and receiver portion of the radar antenna and applies special design methods to minimize the EMI generated by the transmitter and receiver.
TPSU DC-DC Converter
Micross’ TPSU offers state-of-the-art performance and is specifically designed for GaN based synthetic aperture radar (SAR) and solid-state power amplifiers (SSPA) applications. Providing excellent suppression of pulsed load current from output to input, and can be tailored to the specific spacecraft bus and equipment requirements.
