Abstract :
In this paper, a design of an integrated receiver for base-station applications is presented. The receiver is targeted to cover all WCDMA bands and the WiMAX band below 4 GHz. The receiver includes RF front-end, 90-degree phase shifters and programmable baseband filters. The measured voltage gain and NF of the receiver at 2 GHz is 32 dB and 2.6 dB, respectively. The receiver is implemented using a 0.25-mum SiGe BiCMOS process and the power consumption is 432.5 mW from a 2.5 V supply.
