Abstract :
This paper describes a fully integrated 130nm CMOS 2×2 MIMO tri-band dual-mode transceiver for fixed and mobile WiMAX and IEEE 802.11a/b/g/n applications. The transceiver features reduced RF interface (only 4 RF pins) with the wideband circuit topology of the LNA and drive amplifier that minimizes the performance degradation. The measured receive path NF is 3.6~4.2, 4.2~4.7, and 5.4~6.2dB for the 2/3/5GHz bands respectively. The measured integrated phase noise from 1kHz to 10MHz is 0.5/0.8/0.95 rms degree for 2/3/5GHz bands respectively. The transceiver ensures low EVM over the wide dynamic range due to highly linear RX and TX signal paths, and low integrated PLL phase noise characteristics.
