Summary :

A direct conversion receiver for W-CDMA, which consumes extremely low power, is presented. The receiver consists of a low-noise amplifier (LNA) IC, a receiver IC and other passive components such as an RF-SAW (Surface Acoustic Wave) filter. The receiver IC includes a quadrature demodulator (QDEM) with a local oscillator (LO) divider, low-pass filters (LPFs) for channel selection, variable gain amplifiers (VGAs) with dynamic range of 80 dB, and a fractional-N synthesizer. The power consumption for the entire receiver chain was only 30.8 mA at supply voltage of 2.7 V.
