A 3-stream, 802.11n WLAN MIMO transceiver, with fully integrated PAs and LNAs in both 2.4GHz and 5GHz bands, and a T/R switch in the 2.4GHz band, was implemented in a standard 90nm CMOS technology. The transmitter achieves an EVM of -28dB at output power of 19dBm and 17dBm in the 2.4GHz and 5GHz bands, respectively. The transmitter power consumption per Mb(More)
The age reliability of the RF performance of CMOS radio chips must be validated prior to high volume manufacturing. In this paper, we show the results of age simulations on some RF subblock designs used in our 802.11 a/b/g radio chip transceiver for our WLAN card. Transistor age models, based on HCI and NBTI age degradation mechanisms, were derived from(More)
An integrated CMOS 60 GHz phased-array antenna module supporting symmetrical 32 TX/RX elements for wireless docking is described. Bidirectional architecture with shared blocks, mm-wave TR switch design with less than 1dB TX loss, and a full built in self test (BIST) circuits with 5deg and +/-1dB measurement accuracy of phase and power are presented.
