www.DataSheet4U.com PRODUCT SUMMARY SKY74691: Receiver for CDMA Mobile Handset Applications Applications Single mode CDMA handsets After RF LNA signal amplification and filtering from the antenna, the received signal is downconverted from RF to the Intermediate Frequency (IF). The LO_IN signal (pin 39) provides a Local Oscillator (LO) port for the RF mixer. The UHF Voltage Controlled Oscillator (VCO) is buffered and amplified internally, and provides the LO to drive the LO port of a .
