Design of Ku-Band Four-Channel Dual-Polarization Transceiver Module

In order to meet the requirements of Ku-band T/R transceiver module for RF front-end of digital array antenna system, A Ku band four channel dual-polarization T/R transceiver module is Designed. The T/R component integrates four T/R channels with time-sharing operation, each channel can achieve single polarization transmission and dual polarization reception. The module has single-channel emission power
$\geqslant 25 \mathrm{W}$
, receiving gain
$\geqslant 25 \text{dB}$
for horizontal and vertical polarization, NF
$\leqslant 2.5$
db, and good amplitude-phase consistency, which is suitable for systems engineering applications.
