High spurious suppression 60GHz transceiver

This paper proposed a high frequency spurious suppression 60GHz transceiver, which is composed by single module. It works in the 59-64GHz RF frequency with two 2.16GHz bandwidth IF communication channels in the 8.64GHz. The cavity band pass filters are added in the output of the TX and the LO link to realize the high sideband reject and low spurious. This kind of capacity-loading filter can realize low insertion loss and high stop-band suppression to improve the performance of the transceiver. The measured results show that the 60GHz transceiver after adding the cavity filters achieves good performance. The CP1 output power of the TX is higher than 18dBm; the gain and noise figure of the RX is higher than 18dB and lower than 4.5dB; the spurious spectrum suppression of the transceiver is about 40dB than that without cavity filter in the transceiver. As a communication system, it is performed to evaluate the data transmission capabilities between the TX and RX apart from about 5m distance with two waveguide antenna in open-loop way. And the EVM and BER of this communication link is better than 8% and 10^-5 with QPSK modulation.
