MAX2373ETC

RF Amplifiers Overview

The MAX2373ETC is a dual-channel low-noise amplifier (LNA) with integrated step attenuator and variable gain amplifier (VGA). It operates in the 100 MHz to 1 GHz frequency range, specifically optimized for 850 MHz to 940 MHz. Key electrical parameters include a typical power gain of 17 dB at 850-940 MHz, a noise figure of 1.8 dB, and a supply current of 3.5 mA. The device supports a supply voltage range of 2.65 V to 3.3 V and is housed in a 12-TQFN package.

RF Amplifiers Procurement Notes

Verify the specific suffix (+T or +) against your bill of materials, as packaging may vary. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Ensure the operating temperature range meets your environmental requirements. Cross-reference the pinout with official documentation before PCB layout finalization.

RF Amplifiers Selection Notes

Select this component when a compact solution combining amplification, attenuation, and gain control is required. It is ideal for designs needing low noise figure and moderate gain within the sub-1 GHz spectrum. Consider the 12-TQFN package size for space-constrained mobile applications.

RF Amplifiers Part Context

This part belongs to Maxim Integrated's portfolio of RF front-end components. It addresses the need for integrated signal processing in wireless transceivers. The inclusion of VGA and step attenuator reduces external component count compared to discrete LNA solutions.
