1Mbps S-Band Transceiver for Satellite

• Feature

  ･ 1 Mbps high-speed communication (QPSK)

  
  

  ･ Switching between USB/QPSK transmission and coherent (2-way doppler)/incoherent mode is available

  
  

  ･ Status monitoring of the transceiver (transmission and reception status, internal temperature, and the settings for each mode)

  
  

  ･ USB transmission can be achieved with just the upper section of the equipment

  
  

  ･ Designed to withstand the harsh environment of small satellites

  
  

  ･ The 2-way Doppler measurement function controls the transmission frequency
  depending on the reception frequency of the command signal from the ground.

  
  

  ･ Flight Proven

  
  

  ･ ITAR free

  
  

  ･ Made in Japan

  
  

  ･ Lower cost using COTS parts
