Abstract :
A 5 GHz-band SiGe-MMIC transceiver for 324 Mbps transmission is developed. The broadband transceiver characteristics are obtained by utilizing a 5 GHz- band Q-MOD with a circular polyphase filter in the transmitter, and a broadband IFVGA and Q-MIX in the receiver. A developed SiGe-MMIC performs EVM of 3.3%rms and EVM of 5.9%rms in the transmitter and the receiver, respectively using 64-QAM OFDM signal with 120 MHz bandwidth, which corresponds to the data rate of 324 Mbps. Utilizing the developed SiGe-MMIC, the Hi-Vision streaming video data is transmitted without interruption, and is clearly projected onto the TV.
