A dual mode RF receiver for DCS band in 90 nm CMOS is presented. The receiver uses direct conversion for WCDMA mode and uses 100 kHz low IF for GSM/GPRS/EDGE (GGE) mode. The receiver does not use an interstage SAW filter between LNA and mixer. The mixer stage is followed by a variable gain amplifier. Two times LO clock is provided from external source and a divide by two is used to generate quadrature clocks. The receiver has a NF of 2.9 dB and meets all the out of band and in band linearity requirements for both WCDMA and GGE modes
