Abstract :
A fully MMIC 5 GHz-band transceiver module has been developed, which demonstrated high-speed modulation capability of 48 Mbps OFDM/64QAM with 5-7% error vector magnitude (EVM) for 5-6 GHz operations. The module is assembled on a multi-layer ceramic substrate with land grid type RF/DC terminals and measures 11.0/spl times/13.75/spl times/1.1 mm/sup 3/. The module incorporates four MMIC chips operating from /spl plusmn/3 V power supplies and supports a wide range of IF frequencies from 200 MHz to 1.8 GHz.
