ZFM-2+

Overview

The ZFM-2+ is a double balanced mixer manufactured by Mini-Circuits, designed for RF and microwave applications. It operates within a frequency range of 1 MHz to 1000 MHz. The component features a maximum conversion loss of 8.5 dB and supports a maximum continuous wave input power of 17 dBm. It utilizes BNC connectors and is housed in a coaxial construction with CASE K18 packaging. The device exhibits a maximum voltage standing wave ratio of 2.77 and functions reliably across an operating temperature range from -55 °C to 100 °C.

Feature Summary

• Double balanced architecture providing high isolation between ports
• Broadband operation covering frequencies from 1 MHz to 1000 MHz
• Coaxial design with BNC interface connections

Applications

• Frequency upconversion in S-band systems
• RF sensing and connectivity layers for automotive applications
• Signal generation and measurement test equipment

Procurement Notes

Verify the specific ordering suffix when purchasing. The base model designation may differ from variants such as ZFM-2-S+. Confirm that the required connector type and package style match the application requirements before finalizing orders. Ensure compliance with lead time expectations from authorized distributors like Mouser or Digi-Key. Check RoHS status if environmental regulations apply to the project.

Selection Notes

Select this component for applications requiring wide bandwidth coverage up to 1 GHz. Consider the 8.5 dB maximum conversion loss when designing signal chains. The BNC interface simplifies integration into benchtop or modular test setups. Evaluate the thermal limits given the 100 °C maximum operating temperature. Ensure the 17 dBm input power limit is not exceeded to prevent damage.

Part Context

This mixer belongs to Mini-Circuits' portfolio of RF and microwave components. It is commonly used in building blocks for test and measurement solutions. The product line includes various models supporting different frequency ranges and connector types. Mini-Circuits provides engineering support and application notes for integrating these components into complex assemblies like upconverters.

Replacement Considerations

Check for ZFM-2-S+ as a potential variant with similar specifications. Verify compatibility with existing BNC interfaces. Ensure replacement units meet the same 1-1000 MHz frequency range and conversion loss criteria.
