Abstract :
A fully monolithic dual-band radio transceiver chip for 802.11a, 802.11b and 802.11g applications is presented in a 0.25 μm 40 GHz BiCMOS technology. The transceiver chip contains a complete receiver chain with low noise amplifier, mixer, programmable gain amplifier, CCK and OFDM channel filters. In the transmit path, a direct-modulation transmitter with integrated anti aliasing filters and programmable gain control is implemented. The frequency synthesizer consists of a fully integrated VCO, a reference oscillator and a phase locked loop for both supported frequency bands of 2.4 GHz and 5 GHz. For a 3 V power supply, the overall power consumption for 802.11a receive-mode and transmit-mode are 600 mW and 450 mW, respectively.
