The IEEE 802.11ad standard supports PHY rates up to 6.7Gb/s on four 2GHz-wide channels from 57 to 64GHz. A 60GHz system offers higher throughput than existing 802.11ac solutions but has several challenges for high-volume production including: integration in the host platform, automated test, and high link loss due to blockage and polarization mismatch. This paper presents a full-featured 802.11ad...
An IP2 calibration circuit to improve the 2nd-order nonlinearity of mixers in zero or low-IF receivers is presented. The circuit allows the mixers to be optimized independently, and has negligible impact on receiver noise figure, area, and power consumption. A prototype transceiver including the calibration circuitry in 0.13mum CMOS is fabricated. An average IIP2 improvement of 18dB is measured
Under the Mojave configurable computing project, we have developed a system for achieving high performance on an automatic target recognition (ATR) application through the use of configurable computing technology. The ATR system studied here involves real-time image acquisition from a synthetic aperture radar (SAR). SAR images exhibit statistical properties which can be used to improve system performance...
