Description

RF and IF Synthesizers

Fully Programmable via serial bus

3 Volt operation

The ZL20200 is a fully integrated transceiver for dual

band IS136/AMPS handsets. The IF input to the

receive path is amplified and down-converted to

baseband I and Q signals. Gain control is provided.

Baseband filtering is also included. A FM demodulator

is also provided to support AMPS operation.

Small scale package

Applications

The transmit path consists of a quadrature modulator,

gain control at IF and up-conversion to RF. Dual band

RF outputs are provided. The transmit output stages

can be programmed to optimize performance and

current consumption.
