Removes the Requirement for External IF SAW Filter High Power 900MHz and 1900MHz Output Stages Quadrature Modulator DS5241 ISSUE 3.0 December 2000 Ordering Information MGCT02/KG/QP1S MGCT02/KG/QP1T Applications Transmit Modulator and Up-converter in TDMA/ AMPS Mobile Phones The MGCT02 circuit is designed for use in dual band, dual mode cellular 900MHz/PCS1900MHz mobile phones. It can be used for TDMA/AMPS. The MGCT02 is compatible with baseband and mixed signal interface circuits from Zarlink Semiconductor and other manufacturers. System costs have been kept to a minimum by removing the requirement for an additional SAW filter in the transmit IF path. The AGC has been split between RF and IF sections to reduce noise and a low pass filter has been included before the IF variable gain amplifier to remove spurious products produced in the modulator. For CDMA systems the MGCT04 is recommended. Absolute Maximum Ratings Supply voltage (VCC) 4V Control input voltage -0.6V to VCC + 0.6V -55˚C to +125˚C Storage temperature, T...
