The RF2492 is a fully featured dual-band LNA/Mixer and
is usable in a variety of mobile handset applications. The
unique dual IF outputs provide interface to two indepen-
dent IF SAW filters supporting applications such as
TDMA-EDGE where 30kHz and 200kHz bandwidth SAW
filters are used. With independent power management
control pins for the LNAs and mixers, either IF output can
be accessed from either high- or low-band LNAs, provid-
ing maximum flexibility with minimum power usage. Multi-
ple gain control options are provided to achieve a very
large dynamic range for the receiver. A frequency doubler
is included in the LO circuit to generate both high- and
low-band LO signals with a single VCO. The RF2492 is
packaged in a 32 pin, 5mmx5mm, leadless plastic pack-
age.
