High Reliability Space Power Solution for AD9361S-CSH Agile RF Transceiver

Features and Benefits

  • High-reliability, radiation hardened power solution qualified for traditional space applications.
  • Power solution optimized for lowest solution size and low noise performance.

Solution Specifications

High Reliability Space Solution Requirements:

  • Input Voltage: 12VDC
  • Output Voltage: VDDA_X = 1.3V, VDD_INTERFACE = 1.8V, VDD_GPO = 3.3V
  • Output Current: VDDA_X = 1.1A, VDD_INTERFACE = 20mA, VDD_GPO = 1mA
  • Space Qualification: MIL-PRF-38535 Class V
  • Noise: < 65 μVrms
  • Solution Size: < 2200mm2

Traditional space applications require radiation-hardened (RH) power parts; commercial and CSL parts are not suitable.
