Abstract

Future base stations for the narrowband cellular standards, e.g. GSM and D-AMPS, will deploy wideband multicarrier receivers. In these receivers the phase noise of the sampling stage is crucial in order to meet the blocking performance specified in the standards. An expression relating the single sideband phase noise power density to carrier ratio of a sampled signal to that of the sampling clock is derived. The implications of the theory for the clock local oscillator (LO) and clock drive amplifier for a GSM-1900 receiver are shown
