The design, fabrication, and measurements of a 2.4 GHz single-chip CMOS transceiver RF front-end containing a gain-controlled low noise amplifier (LNA), a series type T/R switch, and a power amplifier, to be employed for ISM-band wireless applications is presented. The single-chip RFIC with a chip size of 1.92 × 1.10 mm 2 is fabricated with the 0.25 μm 1P5M standard CMOS process. Extensive measurements in the transmit and receive modes were performed using a FR-4 PCB test fixture which also included an IEEE 802.11b transmit spectrum mask test. The transceiver RFIC for the receiver mode exhibits a gain of 13 dB, a noise figure of 5.7 dB, an input P1dB of -5.3 dBm, and an IIP3 of 1.5 dBm. The CMOS transceiver RFIC performance demonstrated that the standard 0.25 μm CMOS process has a great potential in the transceivers for 2.4 GHz wireless communications.
