LHA-23LN+

Overview

The LHA-23LN+ is a surface-mount MMIC amplifier from Mini-Circuits, designed for broadband operation between 30 MHz and 2 GHz. It features a typical gain of 19.6 dB and a noise figure of 1.5 dB. The device operates on a 5.25 V supply with a current draw of 163 mA. Key performance metrics include a P1dB compression point of 24.2 dBm and an OIP3 of 34 dBm. It utilizes InGaP pHEMT technology and is housed in a compact 3x3 mm QFN-style package.

Feature Summary

• Broadband frequency coverage spanning 30 MHz to 2 GHz
• Low noise figure suitable for sensitive receiver front-ends
• High linearity with significant output power capabilities
• Compact surface-mount packaging for efficient board space utilization

Applications

• CATV signal distribution systems
• Cellular infrastructure base stations
• General purpose RF amplification stages
• Wireless communication transceivers

Procurement Notes

Verify the specific datasheet revision when sourcing, as electrical parameters such as gain and noise figure may vary slightly between manufacturing lots or document updates. Confirm that the ordering suffix matches the required package style and RoHS compliance status. Ensure the supplier provides traceability documentation consistent with Mini-Circuits quality standards for critical RF applications.

Selection Notes

Select this component when a wide bandwidth up to 2 GHz is required alongside low noise performance. Compare against the LHA-23HLN+ if higher output power is needed, noting the difference in supply voltage and technology. Consider the TSS-23LN+ alternative if lower noise is prioritized over output power, while evaluating thermal management requirements for the QFN package in dense layouts.

Part Context

The LHA-23LN+ belongs to the LHA series of monolithic amplifiers from Mini-Circuits. This series focuses on providing versatile solutions for CATV and cellular markets. The component represents a balance between gain, noise, and linearity, utilizing pHEMT technology to achieve performance within a small footprint compared to larger discrete amplifier designs.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate the LHA-23HLN+ for higher power needs or the TSS-23LN+ for lower noise requirements. Verify pinout compatibility and thermal characteristics before swapping any alternative components.
