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 down-
convert 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 communications. The IC is
manufactured on an advanced Silicon Germanium
Bi-CMOS process and is in a 3mmx3mm, 16-pin, lead-
less chip carrier.
