Abstract :
Performance results for a 1-10 GHz chipset developed in a low-cost two-metal 0.18 /spl mu/m-CMOS technology are described. The developed chips include RF and IF amplifiers, down- and up-mixers, VCO, and receiver/transmitter circuits. Each chip´s circuit parameters as well as transistors gate widths are optimized for maximum frequency of operation. The receiver and transmitter chips have a conversion gain higher than 25 dB over 2.4-5.8 GHz, and higher than 16 dB for any other frequency within 1-10 GHz.
