Abstract
A low-noise triple band transmitter for GSM triple-band and WCDMA is presented. By programming parameters, analog baseband and RF frontend can handle signals of different protocols and frequency bands. Novel linearization method is used in LPF and driver amplifier to meet the demand of 3G systems. Noise optimization is also adopted so that our transmitter achieves -157 dBc/Hz noise at 190 MHz frequency offset in WCDMA band, which eliminates external SAW filter.
