چکیده :
A low-profile diplexer is proposed for satellite telemetry, tracking and command (TT&C) applications in S-band frequency within 2.025-2.110/2.200-2.290 GHz. The diplexer consists of two interdigital band-pass filters and a coaxial power divider. The proposed diplexer has high potential for mass production because there is no need to tune the frequency response after fabrication. Also, the structure is lightweight and low-profile so it could be easily integrated into payload transceivers or antennas in small satellites specially CubeSats. A prototype of the proposed diplexer is fabricated and measured. The measured results are in good agreements with simulations. The measured return loss is lower than -15 dB in all ports, insertion loss is less than 0.7 dB and isolation between output ports is better than 55 dB.
