OVERVIEW

Ka Band Transponder System
Space Heritage Q2 2023

Our compact Ka Band Transponder redundant system is a miniaturized plug&play solution for Cubesats and small satellites, specifically designed for high reliability and radiation tolerance.
Suitable for LEO and GEO missions, it offers two Ka Band Transponders and an high gain dual band corrugated horn antenna.
The system has fully configurable operational modes and polarizations. It offers high linearity upconversion for existing on-board S-L band systems or it can act as bent pipe transponder (both regenerative and transparent) together with the integrated receiver.
The internal low power modem is compatible with ASK/OOK/FSK modulations and beacon signal generation.
Support of numerous interfaces and communication protocols ensure compatibility with all popular Cubesat and Smallsat platforms.
Robust construction, component qualification and EMI shielding meet the requirements for space and harsh environments.

APPLICATIONS

  • Cubesat and Smallsat missions
  • FSS communications
  • LEO satellites
  • GEO/GSO TT&C relay satellites
  • BIU satellite services
  • S band Radio up/downconversion
  • IoT for Space
