Design of a Multichannel Ku band Transceiver

The fundamental working principle of a Ku band transceiver which consists of four receiving channels and one transmitting channel is introduced first, and then a detailed analysis is made of the unit circuits and key technology. The test results show that in the working bandwidth of 2 GHz and at -55～+85 ℃, the output power of transmitting channel is up to 31±1 dBm, the gain flatness in band is≤±0.5 dB, the switch isolation is≥90 dB, and the gain of receiving channel is up to 30±1 dB, the noise figure is≤5 dB, and the channel isolation is≥60 dB. The test results demonstrate that the design is valid and meets the requirement.
