Radio Science Subsystem - Specifications

Specifications

• Given a deep space network (DSN) of receivers and/or transmitters.
• A Ka-band traveling wave tube amplifier (K-TWTA) amplifies signals to a transmitting antenna to be received by a distal radio telescope.
• Ka-band translator (KAT) receives signal from a high gain antenna and retransmits the signal back to DSN. In this way the phase and phase-shift resulting from signal modification
• Ka-band exciter (KEX) it supplies telemetry data.
• S-band transmitter is used for radio science experiments. The transmitter receives signal from the RFS, amplifies and multiplies the signal, sending a 2290 MHz signal to the antenna.
• Filter microwave emitter allow only microwaves of a given frequency to be emitted, there is a polarizing element. There are two-bypass filters and a wave-guide. The bypass filters allow different feed polarizations, receiving and transmitting.
