The MAX2585 highly integrated RF-to-baseband receiver
addresses multiband, multimode applications by
providing switched signal paths for cellular AMPS, cellular
CDMA, and PCS CDMA.
The MAX2585 includes an LNA, mixer, baseband filter,
PLL, VGA, and AMPS-grade RF VCO. The entire receiver
eliminates most of the external components found in
other receivers including the IF-SAW filters and multiband
VCOs.
To optimize dynamic range at minimum current, the
MAX2585 implements several programmable gain and
linearity states, each optimized for minimum current
while meeting sensitivity and linearity requirements for
as many as four ranges of received signal strength.
The MAX2585 is available in a 7mm x 7mm, leadless
48-fcLGA package and is specified over the -40°C to +85°C temperature range.
