A 1.4V, 2.4/5 GHz, 90nm CMOS system in a package transceiver for next generation WLAN

We present a 2.4/5GHz system in a package transceiver with integrated 5GHz PA and 10-100MHz signal bandwidth, suitable for next generation WLAN applications. The RXs achieve better than -71dBm sensitivity for 64 QAM while drawing 120mA from a 1.4 supply in a 90nm CMOS process. The integrated 3.3V, 5GHz PA delivers 9dBm average power with an EVM better than -25dB. The transceiver incorporates de-convolved calibration of quadrature mismatches in the transmitter and receiver for improved performance and yield. Micro strip passives are integrated into a flip chip package for both LNA and PA matching elements.
