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 is provided. Baseband filtering is also included.

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. The transmit output stages of ZL20250 can be programmed to optimize performance and current consumption.
