Product Description
The RF2860 is a broadband receiver front-end designed for CDMA PCS
applications. The broadband design makes it a great solution as well for
GPS, IMT-2000 and 2.4GHz applications. It is designed to amplify and
downconvert RF signals, while providing 21.5dB of stepped gain control
range. Features include digital control of LNA gain, TX buffer/enable, and
power down mode. Another feature of the chip is the ability to set the bias
point and RF performance of the LNA and mixer through the ISET1 and
ISET2 resistors respectively. Noise figure, IIP3, and gain are designed to
exceed the IS-98 interim standard requirement for CDMA PCS communi-
cations. The IC is manufactured on an advanced Silicon Germanium
Bi-CMOS process and is in a 3mmx3mm, 16-pin, leadless chip carrier.
