The
electronic instrument is called a transponder. This fixed in the MOM
(and on satellites and spacecrafts in space).
An
antenna array (of planar metallic hollow rods or of dish shaped or
parabolic shaped Reflector) receives electronic signals and
generates a small potential in a circuit connected to it. A TWT
(travelling wave tube) amplifier multiplies that voltage value corresponding to
the signal received.
A transponder receives that amplified signal and decodes the data
and processes it. Then the reply is sent by encoding it and by directing
the microwaves towards the space center on Earth using the high gain
reflector on the MOM.
