Space and Satellite - bus EPS, PDU, RF
High reliability, radiation-hardened power and RF solutions for satellites and space exploration
High reliability, harsh environment exposure, and extended system lifetime requirements – power electronics for space applications must be able to withstand the extremes of radiation, shock, vibration, and temperature. Space mission profiles demand radiation-hardened (rad hard) power conversion and RF solutions that reliably support application needs, such as:
- Satellite bus electrical power systems (EPS)
- Power distribution units (PDU)
- DC-DC converters
- RF communications
- Satellite payload
- DC-DC converters
- RF communications
