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
