RF RF FRONT-END STRUCTURE FOR IMPROVING COMMUNICATION PERFORMANCE OF DEEP SPACE PROBE

摘要

Provided is an RF front end of a deep space probe to increase a communication performance. According to one embodiment of the present invention, the RF front end of a deep space probe comprises: at least one first antenna transmitting/receiving a signal to/from a ground station; second and third antennas transmitting/receiving a signal to/from at least one surrounding device, respectively; a transponder unit including first and second transponders demodulating a first reception signal received through the first antenna and second and third reception signals received through the second and third antennas, respectively, in a preset mode; a coupler unit connected to the third antenna to transmit the third reception signal to the first transponder; and a first diplexer disposed between the transponder unit and the coupler unit to transmit the first reception signal having passed through the coupler unit to the second transponder.
