HMC1082LP4E

Overview

The HMC1082LP4E is a GaAs pHEMT MMIC medium power amplifier from Analog Devices Inc., designed for wideband applications. It operates within a frequency range of 5.5 GHz to 18 GHz, providing a typical gain of 22 dB. The device delivers a P1dB compression point of 24 dBm and an OIP3 of 35 dBm, ensuring robust signal handling capabilities. It functions on a single supply voltage of 5 V with a current consumption of 220 mA. Packaged in a 24-lead LFCSP (LFCSP-24) surface-mount format, it supports operation across temperatures from -40°C to +85°C.

Feature Summary

• Utilizes GaAs pHEMT technology for high-performance RF amplification
• Provides wideband coverage spanning 5.5 GHz to 18 GHz
• Integrates medium power output capabilities with high linearity metrics

Applications

• Point-to-point microwave radio links
• Satellite communication ground stations
• Electronic warfare systems
• Test and measurement instrumentation

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific package marking matches the LFCSP-24 configuration. Ensure environmental compliance documentation aligns with project requirements. Check for any obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when wideband coverage up to 18 GHz is required alongside moderate power output. Evaluate thermal management needs due to the 1.81 W power dissipation rating. Compare against lower-frequency alternatives if bandwidth requirements are less than 5.5 GHz. Consider the 24-lead package size for PCB layout constraints relative to smaller footprint options.

Part Context

This part belongs to the HMC1082 series of GaAs pHEMT MMICs. It serves as a general-purpose driver or medium power amplifier stage. The LP4E suffix indicates the specific leadless package variant. It complements other components in RF front-end designs requiring broadband amplification without discrete matching networks.

Replacement Considerations

Consult official Analog Devices documentation for qualified substitute part numbers. Verify that alternative devices match the 5.5–18 GHz frequency range and 24-lead LFCSP package dimensions. Ensure pin compatibility and electrical specifications meet system requirements before substitution.
