Description
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.
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.
ZL20200 also includes a fractional N RF synthesizer
and two IF synthesizers to provide all local oscillator
signals required.
