HMC921LP4ETR

Overview

The HMC921LP4ETR is a general-purpose RF amplifier manufactured by Analog Devices Inc., designed for operation within the 400 MHz to 2.7 GHz frequency range. It is housed in a 24-QFN (4x4 mm) surface-mount package with exposed pads. The device operates on a single 5V supply and draws approximately 400mA of current. Key electrical specifications include a typical gain of 9dB, a noise figure of 6.5dB, and a 1dB compression point (P1dB) of 33.3dB. This component is intended for applications requiring reliable signal amplification across wide bandwidths.

Feature Summary

• Provides consistent signal amplification across a broad ultra-wideband spectrum from 400 MHz to 2.7 GHz.
• Integrates high linearity performance with a P1dB of 33.3dB to maintain signal integrity under load.
• Features low noise characteristics with a 6.5dB noise figure for sensitive receiver front-end applications.

Applications

• GPS and GNSS receiver systems
• Ultra-wideband communication links

Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm that the 24-QFN package matches PCB footprint requirements. Check datasheet revisions for any parameter updates. Ensure thermal management strategies account for 400mA supply current. Validate frequency response against specific application bandwidth needs before integration.

Selection Notes

Select this component when a wide operational bandwidth covering GPS bands up to 2.7 GHz is required. Consider the 9dB gain and 6.5dB noise figure for sensitivity-critical designs. Evaluate the 24-QFN package size for space-constrained layouts. Assess power consumption constraints relative to the 5V/400mA specification. Compare against other wideband amplifiers if higher gain or lower noise is necessary.
