LHA-1H+

Overview

The LHA-1H+ is a wideband monolithic microwave integrated circuit (MMIC) amplifier designed for surface-mount applications. Fabricated using E-PHEMT technology, it operates within a frequency range of 50 MHz to 6 GHz. The device provides a typical gain of 12.2 dB with a noise figure of 3.4 dB. It requires a single 5 V DC supply and draws approximately 145 mA of current. Key performance metrics include a P1dB compression point of 22.7 dBm and an OIP3 of 38 dBm. The component is housed in an FG873 package and is compliant with RoHS standards.

Feature Summary

• Utilizes advanced E-PHEMT technology for high-performance linear amplification
• Wideband operation covering 50 MHz to 6 GHz frequency range
• Surface-mount design suitable for compact RF circuit integration

Applications

• CATV systems
• DBS receivers
• LTE infrastructure
• Wireless LAN modules

Procurement Notes

Verify the specific part number suffix against official Mini-Circuits documentation to ensure correct pinout and electrical characteristics. Confirm that the FG873 package variant matches your PCB footprint requirements. Check for updated datasheet revisions that may reflect minor manufacturing changes or testing conditions. Ensure compliance with regional environmental regulations such as RoHS if required for your final product assembly.

Selection Notes

Select this component when a wideband solution is required from 50 MHz to 6 GHz with moderate gain and low noise. Consider the 5 V supply requirement and 145 mA current draw for power budget calculations. Evaluate the 22.7 dBm P1dB limit against your system's maximum input signal levels to prevent distortion. Compare the FG873 package dimensions against available board space constraints before finalizing the design.

Part Context

The LHA-1H+ belongs to the LHA series of wideband MMIC amplifiers from Mini-Circuits. This series is characterized by its use of E-PHEMT technology, which offers a balance of gain, noise, and linearity. The H+ suffix typically denotes a specific package configuration or revision within the broader LHA family, distinguishing it from other variants like the LHA-1+ which may have different packaging or slight parameter variations.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. The LHA-1+ is a related model but may differ in packaging or specific electrical tolerances. Cross-reference the FG873 package outline and pin assignments carefully when evaluating alternative components from other manufacturers to ensure mechanical and electrical compatibility.
