♦ Low-Cost Silicon Bipolar Design

The MAX2411A performs the RF front-end transmit/

receive function in time-division-duplex (TDD) communi-

cation 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 MAX2411A includes a low-noise amplifier

(LNA), a downconverter mixer, a local-oscillator buffer, an

upconverter mixer, and a variable-gain power-amplifier

(PA) driver in a low-cost, plastic surface-mount package.

The MAX2411A’s unique bidirectional, differential IF port

reduces cost and component count by allowing the trans-

mit and receive paths to share the same IF filter.

♦ Integrated Upconvert/Downconvert Function

♦ Operates from a Single +2.7V to +5.5V Supply

♦ 3.2dB Combined Receiver Noise Figure:

2.4dB (LNA)

9.2dB (mixer)

♦ Flexible Power-Amplifier Driver:

18dBm Output Third-Order Intercept (OIP3)

35dB Gain-Control Range

♦ LO Buffer for Low LO Drive Level

The LNA has a 2.4dB typical noise figure and a -10dBm

input third-order intercept point (IP3). The downconvert-

er mixer has a low 9.2dB noise figure and 4dBm input

IP3. Image and local-oscillator filtering are implemented

off-chip for maximum flexibility. The PA driver amplifier

has 15dB of gain, which can be reduced over a 35dB

range. Power consumption is only 60mW in receive

mode and 90mW in transmit mode and drops to less

than 3µW in shutdown mode.

♦ Low Power Consumption:

60mW Receive

90mW Full-Power Transmit

♦ 0.3µW Shutdown Mode

♦ Flexible Power-Down Modes Compatible with

MAX2510/MAX2511 IF Transceivers

_______________Ord e rin g In fo rm a t io n

For applications requiring separate, single-ended IF

inp ut a nd outp ut p orts , re fe r to the MAX2410 d a ta

sheet. For applications requiring only a receive func-

tion, Maxim offers a low-cost downconverter with LNA

(see the MAX2406 data sheet).
