3. TECHNICAL BRIEF The amplifier outputs drive the RF ports of the quadrature RF-to-baseband downconverters. The downconverted baseband outputs are multiplexed and routed to lowpass filters (one I and one Q) having passband and stopband characteristics suitable for GMSK processing. These filter circuits include DC offset corrections. The filter outputs are buffered and passed on to the MSM6275 IC for further processing (an interface shared with the RFR6250 UMTS receiver outputs). - 21 -

downconverted baseband outputs are multiplexed and routed to lowpass filters (one I and one Q)
having passband and stopband characteristics suitable for GMSK processing. These filter circuits
include DC offset corrections. The filter outputs are buffered and passed on to the MSM6275 IC for
further processing (an interface shared with the RFR6250 UMTS receiver outputs).
