SA900 - I/Q transmit modulator

Description

The SA900 is a monolithic high performance, multi-function transmit modulator for use in cellular radio applications, fabricated in QUBiC BiCMOS technology.

Features

  • both analog (AMPS) mode and complex, I/Q digital (NADC IS.
  • 136) mode quadrature modulation functions, a PLL synthesizer with VCO, crystal oscillator, programmable prescalers and Gilbert cell multiplier phase detector with programmable charge pump output. The DUALTX output can be used in DUAL mode cellular phone.
