Abstract :
A 2.5V DECT RF transceiver IC utilizes a low-IF receiver architecture with a 4th-order complex band-pass filter. The transmitter utilizes direct VCO modulation and a frequency doubler. The 9.4mm/sup 2/ die is implemented in a 0.25/spl mu/m CMOS process. The receiver sensitivity is -94dBm, and supply current is 75mA. Transmitter output power is 0dBm with a supply current of 33mA.
