Product Description
The RF2460 is a receiver front-end designed for the receive section of PCS CDMA and W-CDMA applications. It is designed to amplify and downconvert RF signals while providing 29dB of stepped gain control range and features digital control of LNA gain, mixer gain, and power down mode. A further feature of the chip is adjustable IIP3 of the LNA and mixer using an off-chip current setting resistor. Noise Figure, IP3, and other specs are designed to be compatible with the IS-98B for CDMA PCS communications. The IC is manufactured on an advanced Silicon Germanium Bi-CMOS process and is assembled in a 20-pin, QFN package with an exposed die flag.
