80. CO is divided by four or two respectively and connected via an output buffer to the appropriate single ended output pin This configuration ensures minimum noise level The 8PSK transmitter supports power class E2 for GSM850 and GSM900 as well as for DCS1800 and PCS1900 The digital transmitter architecture is based on a polar modulation architecture where the analog modulation data rectangular coordinates is converted to digital data stream and is subsequently transformed to polar coordinates by means of a CORDIC algorithm The resulting amplitude information is fed into a digital multiplier for power ramping and level control The ready processed amplitude signal is applied to a DAC followed by a low pass filter which reconstructs the analog amplitude information The phase signal from the CORDIC is applied to the Sigma Delta fractional N modulation loop The divided output of its associated VCO is fed to a highly linear amplitude modulator recombining amplitude and phase information The output of the amplitude modulator is connected to a single ended output RF PGA for digitally setting the wanted transmit power The PA interface of SMARTi PM supports direct control of standard dual mode power amplifiers PA s which usually have a power control input VAPC and an optional bias control pin VBIAS for efficiency enhancement In GMSK mode the PA is in saturated high efficiency mode and is controlled via its VAPC pin directly by the baseband rampi
