Overview

The ZFL-1000LN+ is a high-performance coaxial low-noise amplifier from Mini-Circuits designed for wideband operation from 100kHz to 1GHz. Housed in a rugged Y460 module with SMA connectors, it provides a stable 20dB gain and a low noise figure of 2.9dB for signal conditioning in sensitive RF environments.

Why Choose This Part

The module features a convenient chassis-mount design with SMA connectors, eliminating the need for custom PCB layout during prototyping. It offers a flat gain profile and a low noise figure of 2.9dB while operating from a single 15V supply at 60mA.

Applications

VHF/UHF Receiver Front-Ends
Boosting weak signals in communication systems operating across the 100kHz to 1GHz range.
Lab Prototyping
Acting as a general-purpose gain block for RF bench testing and system integration.
Cellular Infrastructure
Providing low-noise amplification in cellular base station and repeater sub-assemblies.
Small Signal Amplification
Increasing the dynamic range of measurement equipment when evaluating low-power RF signals.
