LHA-83W+

Overview

The LHA-83W+ is a wideband low-noise amplifier from Mini-Circuits, designed for operation across the 10 MHz to 4.5 GHz frequency range. It delivers a typical gain of 20 dB with a noise figure of 2.5 dB. The device features a high output IP3 of +30 dBm and an output P1dB of +17 dBm. Housed in a compact SMT package measuring 0.126 x 0.098 inches, it operates on a single 5V supply while consuming only 20 mA of current.

Feature Summary

• Provides wideband amplification covering 10 MHz to 4.5 GHz
• Delivers high linearity with +30 dBm output IP3
• Maintains low noise figure of 2.5 dB for signal integrity
• Operates efficiently on a single 5V power supply

Applications

• Wireless infrastructure base stations
• Test and measurement equipment front ends
• Satellite communication systems
• Broadband data transmission links

Procurement Notes

Verify the specific ordering suffix against the official Mini-Circuits datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the required operating temperature range aligns with the commercial grade rating. Ensure PCB layout supports the specified impedance matching network for optimal performance at the target frequencies.

Selection Notes

Select this component when broad frequency coverage is required alongside moderate gain and high linearity. It is suitable for applications where a low noise figure is critical but extreme sensitivity is not the primary constraint. Consider the single-supply requirement and compact footprint as advantages for space-constrained designs.

Part Context

This model belongs to the LHA series of wideband amplifiers, which are engineered for general-purpose RF applications. Unlike narrowband variants, this unit offers consistent performance across multiple decades of frequency. It complements other Mini-Circuits components by providing stable gain without requiring complex tuning networks.

Replacement Considerations

Direct substitutes include the LHA-83+ and LHA-83+. Verify pin compatibility and thermal characteristics before swapping. Alternative models may offer different gain or noise figures but might require circuit redesign.
