Description

Designing reliable power solutions for space-grade RF systems presents unique challenges, particularly when strict noise, size, and reliability constraints must be met. The AD9361S-CSH—engineered for commercial space high-reliability applications—requires radiation- hardened power components, as standard commercial or CSL-grade devices do not meet the necessary qualification standards. Additionally, the AD9361S-CSH is sensitive to power supply noise and requires a low noise solution for 1.3V main supply, VDD_INTERFACE, and VDD_GPO supply. These challenges are addressed with a high-reliability, radiation-hardened power solution tailored for traditional space environments. Optimized for compact form factor and low-noise performance - ideal for space-constrained satellite communication systems.

Applications

  • Space Satellite Communications

Features & 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.
