Description

The MGCR01 is designed for use in dual mode

mobile phones (TDMA/AMPS and CDMA/AMPS).

The circuit provides IF ampli鏗乧ation with gain control

and differential I and Q baseband outputs. The

MGCR01 interfaces directly with MGCM01 for

TDMA/AMPS (using 60kHz low IF) and MGCM03 or

MGCM04 for CDMA and AMPS applications. The on

chip oscillator and prescaler are also compatible with

the PLL synthesisers on these devices.
