The MAX2371/MAX2373 wideband low-noise amplifier(LNA) ICs are designed for direct conversion receiver(DCR) or very low intermediate frequency (VLIF) receiverapplications. They contain single-channel, single-endedLNAs with switchable attenuator and automatic gain control(AGC) intended as a low-noise gain stage. Thesedevices provide high gain-control range (typically 60dB)at radio frequency (RF) with excellent noise and reverseisolation characteristics.The MAX2371/MAX2373 can work over the frequencyrange from 100MHz to 1GHz. In practice, only a narrowband is needed in each application, so different matchingcircuits can be applied. The devices are dynamically configuredthrough the digital/analog control pins to selecteither maximum gain and low noise figure or power-savingmode. In addition, the MAX2371/MAX2373 featurehigh/low-current modes, high/low attenuation modes, linearlycontrolled gain states, and shutdown mode.ApplicationsDirect Conversion Receiver (DCR)Very Low IF Receiver
