Coaxial horn approach is selected to
guarantee that the phase centers of
the two bands are at the same point.
Ka horn is coaxially inside the X horn
(not seen due to the sunshield).
Mechanical and electrical design
complexity is increased.
Thermal Design is also a challenge
since the satellite will orbit Mercury
(temperature higher than 300 ºC).

Band Stop Filters
Band-Stop response achieved with a reflective approach to provide a relative
bandwidth of 1.5% (BW of the rejected band).
Reflective approach is based on a Septum Polarizer, a TE111 CP Bandpass Filter
and a Load. The S11 of the Bandpass Filter is the S21 of the BandStop Filter.
Thermal stabilization with Super-Invar ( 2 MHz frequency shift for -20ºC/
+70ºC)
