Transmit Circuit for TDMA/AMPS

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.

FEATUREs
• Dual RF Ports for 900MHz and 1900MHz
• AGC Amplifier with 90dB of Variable Gain, Fully Compensated for Temperature
• On-chip Active Filter. Removes the Requirement for External IF SAW Filter
• High Power 900MHz and 1900MHz Output Stages
• Quadrature Modulator

APPLICATIONs
• Transmit Modulator and Up-converter in TDMA/AMPS Mobile Phones
