Low-Cost RF Up/Downconverter
with LNA and PA Driver
________________General Description
The MAX2410 performs the RF front-end transmit/receive
function in time-division-duplex (TDD) communication
systems. It operates over a wide frequency range and
is optimized for RF frequencies around 1.9GHz.
Applications include most popular cordless and PCS
standards.
The MAX2410 contains a low-noise amplifier (LNA), a
downconverter mixer, a local-oscillator (LO) buffer, an
upconverter mixer, and a variable-gain power-amplifier
(PA) driver in a low-cost, plastic surface-mount package.
The LNA has a 2.4dB (typical) noise figure and a
-10dBm input third-order intercept point (IP3). The down-
converter mixer has a low 9.8dB noise figure and a
3.3dBm IP3. Image and LO filtering are implemented off-
chip for maximum flexibility. The PA driver has 15dB of
gain, which can be reduced over a 35dB (typical) range.
Power consumption is only 60mW in receive mode or
90mW in transmit mode and drops to less than 0.3µW in
shutdown mode.
A similar part, the MAX2411A, features the same func-
tionality as the MAX2410 but offers a differential
bidirectional (transmit and receive) IF port. This allows
the use of a single IF filter for transmit (TX) and receive
(RX). For applications requiring a receive function only,
consult the data sheet for the MAX2406, a low-cost
downconverter with low-noise amplifier.
