Overview

The ZFL-500+ is a wideband coaxial RF amplifier designed for the 50kHz to 500MHz frequency range. It provides a stable 25dB gain and is housed in a rugged, shielded metal case with SMA connectors for high reliability in demanding environments. This module operates from a 15V supply and consumes 80mA, making it suitable for both laboratory and industrial applications.

Why Choose This Part

The ZFL-500+ features a patented wideband design that offers consistent performance from very low frequencies (50kHz) up to 500MHz. Its rugged, shielded enclosure minimizes electromagnetic interference, while the chassis-mount form factor with SMA connectors ensures secure physical and electrical integration.

Applications

VHF/UHF Signal Boosting
Ideal for amplifying low-level signals in the VHF and UHF bands for communications and radio monitoring.
Laboratory Instrumentation
Provides a flat gain response for test and measurement setups requiring signal isolation or pre-amplification.
Wideband Receiver Front-Ends
Used as an initial gain stage in wideband receivers to improve system sensitivity across a 500MHz bandwidth.

Getting Started

Integration requires a stable 15V DC power supply capable of providing at least 80mA to the solder terminal or BNC/SMA power feed. Ensure the input signal level does not exceed the P1dB compression point of 9dBm to maintain linearity. The module can be mounted directly to a chassis or thermal heat sink using the integrated mounting holes.
