MAX2373EGC+

RF Amplifiers Overview

The MAX2373EGC+ is a wideband low-noise amplifier (LNA) IC designed for direct conversion receiver (DCR) or very low intermediate frequency (VLIF) applications. It operates within a frequency range of 100 MHz to 1 GHz, covering specific bands such as 850 MHz to 940 MHz and GPS frequencies. The device features a typical noise figure of 1.8 dB and provides 17 dB gain with a P1dB of 19.5 dBm. It requires a supply voltage between 2.65 V and 3.3 V. Packaged in a compact 12-QFN (3x3 mm) exposed pad format with a height of 0.90 mm, it supports general-purpose RF amplification tasks.

RF Amplifiers Procurement Notes

Verify the exact ordering suffix against the manufacturer's current catalog to ensure compatibility with required packaging options, such as tape and reel versus tube configurations. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices Inc. before finalizing procurement plans to avoid supply chain discrepancies.

RF Amplifiers Selection Notes

Select this component when a wideband LNA is required for DCR or VLIF topologies operating below 1 GHz. Consider the 1.8 dB noise figure and 17 dB gain for sensitivity-critical designs. Ensure the system power supply aligns with the 2.65 V to 3.3 V range and that the PCB layout accommodates the 12-QFN exposed pad for optimal thermal and electrical performance.

RF Amplifiers Part Context

The MAX2373 is part of the MAX2371/MAX2373 family of wideband LNAs from Maxim Integrated, now part of Analog Devices Inc. These devices are engineered to provide high linearity and low noise in compact packages, addressing the needs for modern wireless communication systems requiring efficient signal conditioning in the sub-GHz frequency bands.
