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.  
FM Demodulator  
RF and IF Synthesizers  
Fully Programmable via serial bus  
3 Volt 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.
