The RF2461 is a receiver front-end designed for the
receive section of dual-mode CDMA/FM cellular applica-
tions. It is designed to amplify and downconvert RF sig-
nals, while providing 30dB of stepped gain control range.
Features include digital control of LNA gain, mixer gain,
and power down mode. Another 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 interim
standard for CDMA cellular communications. The IC is
manufactured on an advanced Silicon Germanium HBT
process and is in a 4mmx4mm, 20-pin, leadless chip car-
rier.
