Abstract
This paper describes a fully integrated 130 nm CMOS
2x2 MIMO tri-band dual-mode transceiver for fixed and mobile
WiMAX and IEEE 802.11a/b/g/n applications. The proposed
transceiver features reduced RF interface (only 4 RF pins) with
the wideband circuit topology of the LNA and drive ampli fier that
minimizes the performance degradation. With carefully chosen
LO frequency planning, the transc eiver is capable of operating
at 2.3–2.7 GHz, 3.3–3.9 GHz, and as well as 5.1–5.9 GHz bands
