HMC943LP5E

Overview

The HMC943LP5E is a GaAs pHEMT MMIC power amplifier operating from 24 GHz to 31.5 GHz. It delivers 1.5 watts of output power with a gain of 18 dB and an efficiency of 20 percent. The device requires a single positive supply voltage ranging from 6 V to 8 V, drawing approximately 700 mA of current. Packaged in a compact LFCSP-32 surface-mount footprint, it supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes GaAs pHEMT technology for high-performance RF amplification
• Provides high output power suitable for millimeter-wave applications
• Integrated monolithic microwave integrated circuit design
• Surface-mount package optimized for automated assembly

Applications

• Point-to-point microwave radio links
• Satellite communication ground stations
• Millimeter-wave radar systems
• Test and measurement equipment

Procurement Notes

Verify the specific frequency range against your system requirements, as datasheets may list 24-31.5 GHz or 24-34 GHz variants. Confirm thermal management capabilities for the LFCSP-32 package under continuous wave conditions. Ensure supply chain authenticity through authorized Analog Devices distributors due to limited availability status in some regions.

Selection Notes

Select this component when high output power is required in the K-band and Ka-band ranges. Consider the thermal resistance of the PCB layout to maintain junction temperatures within specifications. Evaluate the need for external matching networks if operating at band edges outside the standard 24-31.5 GHz range.

Part Context

This part belongs to the HMC943 series of high-power amplifiers from Analog Devices. It complements lower-power variants like the HMC943ALP5DE by offering higher wattage capability. The LP5E suffix indicates the specific lead-free package configuration compatible with standard SMT reflow processes.

Replacement Considerations

The HMC943ALP5DE is a documented substitute variant within the same family. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference datasheet revisions to ensure performance parameters meet current design constraints.
