MAX2373ETC+T

RF Amplifiers Overview

The MAX2373ETC+T is a low-noise amplifier (LNA) IC featuring an integrated step attenuator and variable gain amplifier. It operates within a frequency range of 100 MHz to 1 GHz, with specific general-purpose applications noted for 850 MHz to 940 MHz. The device provides a typical noise figure of 1.8 dB and a nominal small-signal gain of 15 dB. It includes a 20 dB step attenuator for signal control. The component is housed in a compact 12-TQFN package measuring 3x3 mm.

RF Amplifiers Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm packaging type and temperature grade. Ensure the procurement source provides valid traceability for the +T tape and reel configuration. Cross-reference the manufacturer's latest datasheet to confirm current status and any potential obsolescence notices before finalizing orders.

RF Amplifiers Selection Notes

Select this component when a combined solution for amplification, attenuation, and gain control is required in a single package. Consider the 12-TQFN footprint for space-constrained designs. Evaluate the 1.8 dB noise figure against system sensitivity requirements. Confirm that the 100 MHz to 1 GHz operating range aligns with the target application bandwidth.

RF Amplifiers Part Context

This part belongs to the Maxim Integrated line of RF amplifiers, now under Analog Devices. It is designed for general-purpose use in wireless infrastructure and portable devices. The integration of a VGA and step attenuator reduces bill-of-materials count compared to discrete solutions.

RF Amplifiers Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Do not assume pin-to-pin compatibility with other LNA models without verifying electrical parameters and package dimensions.
