A transceiver module operating at the 220 GHz frequency band was developed， consisting of three parts： a local oscillator chain， a transmitter chain， and a receiver chain， featuring high integration. A 218-226 GHz waveguide bandpass filter was designed to suppress spurious signals in the chain. The filter adopts a dual-mode resonant cavity structure to introduce a transmission zero on the left side of the passband， which suppresses the 214 GHz spurious signal by 60 dBc. An improved E-plane magic-T structure was used to form a four-way power combining amplifier to meet the requirement of transmit power. This module achieves a power combining efficiency of 72.5% and the output power is higher than 82 mW. The measured results show that in the 219.5-221 GHz frequency range， the transmit power is 82-95 mW， the noise figure of the receiver is less than 7.1 dB， the receiver gain is 5.1-6.0 dB， and the volume of module is 65×70×30 mm3.
