Abstract

WLAN (IEEE 802.11a)/VMAN (IEEE 802.16a) dual mode transceiver chip has been proposed, designed and fabricated. Transceiver RF IC chip with packaged size of 6 mm*6 mm was fabricated using 0.25 um SiGe BiCMOS process. Power amplifier and PLL/VCO chip were fabricated using the same process. Ceramic front-end filter were also fabricated for WLAN/WMAN frequencies. To make compact transceiver system, these chips was mounted on 2 cm*2 cm double side PCB. The full system has been tested with external ADC/DAC and baseband modem. The measured results show that fabricated transceiver system meets the requirements for WLAN/WMAN standards
