Honor Roll

  • Rabi Narayan Rath
  • Pankaj Kumar Meena
Varuna’s SSPA amplifies a low-power radio signal and delivers it to the antenna for transmission to ground control.

Space Readiness

The amplifier was meticulously optimized to certify stability and longevity in orbit.
  • Thermal management is carefully implemented into the design with high-conductivity materials and using thermal vias in the circuit board. This directs the heat along efficient conduction paths to the payload radiator and dissipates it at acceptable levels.
