The MAX2510 is a highly integrated IF transceiver for
digital wireless applications. It operates from a +2.7V to
+5.5V supply voltage and features four operating
modes for advanced system power management.
Supply current is reduced to 0.2µA in shutdown mode.
In a typical application, the receiver downconverts a
high IF/RF (up to 600MHz) to a low IF (up to 30MHz)
using a double-balanced mixer. Additional functions
included in the receiver section are an IF buffer that
can drive an off-chip filter, an on-chip limiting amplifier
offering 90dB of received-signal-strength indication
(RSSI), and a robust differential limiter output driver
designed to directly drive a CMOS input. The transmit-
ter section upconverts I and Q baseband signals to an
IF in the 100MHz to 600MHz range using a quadrature
modulator. The transmit output is easily matched to
drive a SAW filter with an adjustable output from 0dBm
to -40dBm and excellent linearity.
The MAX2511 has features similar to the MAX2510, but
upconverts a low IF with an image-reject mixer. The
MAX2511 downconverter also offers image rejection
with a limiter/RSSI stage similar to that of the MAX2510.
