LHA-13LN+

Overview

The LHA-13LN+ is a monolithic microwave integrated circuit (MMIC) amplifier manufactured by Mini-Circuits. It operates within a frequency range of 1 MHz to 1 GHz and utilizes pHEMT technology on a silicon substrate. The device provides a typical gain of 20.1 dB with a noise figure of 1.2 dB. It functions at an operating supply voltage between 3 V and 5 V, drawing approximately 143 mA. Key performance metrics include a P1dB compression point of 24.2 dBm and an OIP3 of 36.4 dBm. The component is housed in a compact SOT-89-4 or 12-MCLP surface-mount package, suitable for CATV and cellular applications.

Feature Summary

• Utilizes pHEMT technology for low noise and medium power linear amplification
• Designed for wideband operation from 1 MHz to 1 GHz
• Surface-mount construction for automated assembly integration

Applications

• CATV signal distribution systems
• Cellular infrastructure front-end modules
• Wireless communication base stations

Procurement Notes

Verify the specific package variant (SOT-89-4 vs. MCLP) against the schematic footprint before ordering. Confirm that the 5V supply rail matches the datasheet requirements for optimal gain and linearity. Ensure thermal management strategies account for the 3.3W power dissipation capability during high-duty cycle operations.

Selection Notes

Select this component when a wide bandwidth covering HF through UHF bands is required alongside low noise performance. It is appropriate for designs needing moderate output power without external matching networks. Consider the package size constraints relative to the available PCB real estate for the chosen surface-mount option.
