HMC375LP3E

Overview

The HMC375LP3E is a GaAs pHEMT MMIC Low Noise Amplifier designed for the 1.7 to 2.2 GHz frequency range. It operates on a single 5 V supply with a current consumption of 90 mA. The device provides a typical gain of 14 dB and a noise figure of 1 dB. Key performance metrics include a P1dB compression point of 20 dBm and an OIP3 of 35 dBm. It features an input return loss of 25 dB and dissipates 878 mW of power. The component is housed in a QFN-16 surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• High dynamic range GaAs pHEMT MMIC technology
• Integrated low noise amplification for cellular basestations
• Surface-mount QFN-16 packaging

Applications

• GSM cellular basestation front-end
• CDMA cellular basestation front-end

Procurement Notes

Verify availability status as the manufacturer has scheduled this part for obsolescence and discontinuation. Confirm that the specific lot or revision matches design requirements before procurement. Check for valid RoHS compliance documentation. Ensure storage conditions account for moisture sensitivity classification. Validate that the discontinued status does not impact long-term supply chain stability for existing designs.

Selection Notes

Select this component for narrow-band, low-power RF applications requiring high linearity in the 1.7 to 2.2 GHz band. The 14 dB gain and 1 dB noise figure suit sensitive receiver front-ends. Consider the 5 V supply requirement and 90 mA current draw for power budgeting. The QFN-16 package dictates PCB layout constraints. Evaluate thermal dissipation capabilities given the 878 mW power rating.

Part Context

This part belongs to the HMC375 series of low noise amplifiers from Analog Devices. It utilizes GaAs pHEMT MMIC technology for superior performance in wireless communications. The LP3E suffix indicates a lead-free, RoHS-compliant variant in a QFN-16 package. It is distinct from other HMC series amplifiers by its specific frequency coverage and high dynamic range characteristics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the scheduled obsolescence, alternative components must be identified through independent engineering analysis rather than direct cross-reference lists.
