________________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.

MAX2410 Low-Cost RF Up/Downconverter with LNA and PA Driver PA Driver The PA driver typically has 15dB of gain, which is adjustable over a 35dB range via the GC pin. At full gain, the PA driver has a noise figure of 3.5dB at 1.9GHz. For input and output matching information, refer to the Typical Operating Characteristics for plots of PA Driver Input and Output Impedance vs. Frequency. Receive Mixer The receive mixer is a wideband, double-balanced design with excellent noise figure and linearity.
