ZFL-500+

Overview

The Mini-Circuits ZFL-500+ is a low-power, wideband coaxial amplifier designed for operation within the 0.05 MHz to 500 MHz frequency range. It provides a nominal gain of 25 dB with a typical noise figure of 4.2 dB. The device operates on a single +15 V supply voltage and draws approximately 80 mA of current. It features a rugged, shielded case construction suitable for demanding environments.

Feature Summary

• Wideband amplification capability spanning from 0.05 MHz to 500 MHz
• Low noise figure performance for signal integrity
• Rugged, shielded case design for environmental protection

Applications

• RF and IF signal processing systems
• General purpose amplifier circuits
• Test and measurement equipment front ends

Procurement Notes

Verify the specific suffix (e.g., BNC connectors) against project requirements as connector types may vary. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to procurement. Ensure supply voltage and current ratings align with system power constraints.

Selection Notes

Select this component when a wideband, low-noise solution is required below 500 MHz. Consider the 25 dB gain and 80 mA current draw relative to system power budgets. Evaluate the rugged shielded package for mechanical durability needs in the target application environment.

Part Context

The ZFL-500+ belongs to the Mini-Circuits ZFL series of low-power coaxial amplifiers. This series utilizes an interchangeable platform design, allowing for flexibility in integration across various RF applications while maintaining consistent electrical performance characteristics within the specified frequency band.

Replacement Considerations

The ZFL-500-BNC is a documented variant within the same family, differing primarily in connector type. Verify interface compatibility before substitution. No other direct cross-model replacements are confirmed in public documentation.
