RF2861 CDMA Low Noise Amplifier/Mixer 900MHz Downconverter

The RF2861 is a receiver front-end for CDMA cellular applications, including JCDMA and CDMA450. It is designed to amplify and downconvert RF signals, using a three gain state LNA to obtain 17dB of stepped gain control. Features include digital control of LNA gain and power down mode, along with an integrated TX LO buffer amplifier. Another feature of the chip is adjustable IIP3 of the LNA and mixer using off-chip current setting resistors to allow for minimum DC current consumption. Noise figure, IIP3, and other specs are designed to be compatible with the TIA/EIA 98D standard for CDMA cellular communications. The IC is manufactured on an advanced Silicon Germanium Bi-CMOS process and is in a 3mm x 3mm, 16-pin, QFN.
