♦ Low-Cost Silicon Bipolar Design
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 op timize d for RF fre q ue nc ie s a round 1.9GHz.
Applications include most popular cordless and PCS
standards.
♦ Integrated Upconvert/Downconvert Function
♦ Operates from Single +2.7V to +5.5V Supply
♦ 3.2dB Combined Receiver Noise Figure:
2.4dB (LNA)
9.8dB (Mixer)
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 ha s a 2.4d B (typ ic a l) nois e fig ure a nd 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.
♦ Flexible Power-Amplifier Driver:
18dBm Output Third-Order Intercept (OIP3)
35dB Gain Control Range
♦ LO Buffer for Low LO Drive Level
♦ Low Power Consumption:
60mW Receive
90mW Full-Power Transmit
♦ 0.3µW Shutdown Mode
♦ Flexible Power-Down Modes Compatible with
MAX2510/MAX2511 IF Transceivers
A similar part, the MAX2411A, features the same func-
tiona lity a s the MAX2410 b ut offe rs a d iffe re ntia l
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.
