LNAs with Step Attenuator and VGA

General Description

Features

The MAX2371/MAX2373 wideband low-noise amplifier

(LNA) ICs are designed for direct conversion receiver

(DCR) or very low intermediate frequency (VLIF) receiver

applications. They contain single-channel, single-ended

LNAs with switchable attenuator and automatic gain con-

trol (AGC) intended as a low-noise gain stage. These

devices provide high gain-control range (typically 60dB)

at radio frequency (RF) with excellent noise and reverse

isolation characteristics.

♦ Low Noise Figure (1.8dB typical)

♦ High Small-Signal Gain (15dB Nominal)

♦ Wide Frequency Range of Operation

(100MHz to 1GHz)

♦ 20dB Step Attenuator

♦ 45dB AGC Range Excluding Step Attenuator

♦ 2.65V to 3.3V Single-Supply Operation

♦ Shutdown Mode

The MAX2371/MAX2373 can work over the frequency

range from 100MHz to 1GHz. In practice, only a narrow

band is needed in each application, so different matching

circuits can be applied. The devices are dynamically con-

figured through the digital/analog control pins to select

either maximum gain and low noise figure or power-saving

mode. In addition, the MAX2371/MAX2373 feature

high/low-current modes, high/low attenuation modes, lin-

early controlled gain states, and shutdown mode.

♦ 3.5mA Supply Current, Adjustable Down to 2.5mA

♦ 40dB Reverse Isolation
