The RF2456 is a receiver dual downconverter designed
for the receive section of dual-mode CDMA/FM cellular
applications. It is designed to downconvert RF signals
while providing 13dB gain in CDMA mode, and 7dB gain
in FM mode. It also features digital control of IF output
selection and power down mode. Noise Figure, IP3, and
other specs are designed to be compatible with the IS-95
Interim Standard for CDMA cellular communications. The
IC is manufactured on an advanced Silicon Bipolar pro-
cess and packaged in an SSOP-16.
