SA900 I/Q Transmit Modulator

The SA900 is a monolithic high performance, multi-function transmitmodulator for use in cellular Radio applications, fabricated in QUBiCBiCMOS technology. The SA900 features both Analog (AMPS)mode and complex, I/Q digital (NADC IS,136) mode quadraturemodulation functions, a PLL synthesizer with VCO crystal Oscillator programmable prescalers and Gilbert cell multiplier phase detectorwith programmable Charge Pump output. The DUALTX output canbe used in DUAL mode cellular phone applications with the AMPSand NADC modulation being applied to the I/Q baseband inputs.The DUALTX output also provides 6-bit power control with 40dB ofgain control in 0.63dB steps. In addition, buffered crystal oscillatorprogrammable prescaler outputs are provided to support systemclock reference needs. Programming of the SA900 functions arerealized by a high speed 3-wire serial Interface The SA900 CAN beprogrammed into a sleep mode (low current mode providing crystaloscillator and Master Clock functions), a standby mode (providingcrystal Oscillator Master Clock System Clock 1 and Transmit LObuffer functions), and the AMPS mode and the DUAL modeconfigurations.
