Abstract :
A 5 GHz direct-conversion receiver for the IEEE 802.16 wirelessHUMAN/IEEE 802.11a WLAN standard has been designed and fabricated in a 0.25-mum SiGe BiCMOS technology. It contains a complete receiver chain including low noise amplifier, mixers, gain-programmable baseband amplifiers and tunable baseband low-pass filters. The frequency synthesizer and VCO work at either WiMAX or WLAN mode in 5 GHz unlicensed band. The chip has 5.88 dB overall chain noise figure, and consumes 360 mW with a 3 V power supply
