Description
The ZL20250 is a fully integrated transceiver for
multimode IS136/GSM/GPRS/EDGE handsets. The
dual IF inputs to the receive path are amplified and
down-converted to baseband I and Q signals. Gain
control and baseband filtering are provided. A FM
demodulator is also provided where AMPS
compatibility is required.
The transmit path consists of a quadrature modulator,
gain control at IF and up-conversion to RF. Dual band
RF outputs are provided.
ZL20250 also includes a fractional N RF synthesizer
and two IF synthesizers to provide all local oscillator
signals required.
Flexible programming is provided via a 3 wire serial
bus. Additional control pins allow accurate timing
control when switching between modes.
