LFCN-5850+

Overview

The LFCN-5850+ is an LTCC low-pass filter manufactured by Mini-Circuits, designed for signal conditioning in RF and microwave applications. It operates with a cutoff frequency of 5850 MHz and maintains a system impedance of 50 Ohms. The device supports DC pass-through from input to output and offers excellent power handling capabilities rated at 8W. Packaged in the FV1206 surface-mount format, it provides high isolation to ground when required.

Feature Summary

• LTCC construction for compact SMD integration
• DC pass-through capability between input and output
• High power handling capacity of 8W
• High isolation to ground configuration

Applications

• S-band upconverter assemblies
• RF signal conditioning circuits
• Microwave filtering systems

Procurement Notes

Verify the specific suffix designation against the official datasheet to confirm functional variations. The standard model supports DC pass-through; however, alternative suffixes may alter isolation characteristics or grounding requirements. Ensure the selected variant matches the circuit's impedance and power handling needs before procurement.

Selection Notes

Select this component for applications requiring a 5850 MHz cutoff in a small footprint. Consider the 8W power rating for high-power environments. Verify if DC continuity is necessary, as specific suffixes may modify isolation properties. Confirm the FV1206 package compatibility with the target PCB layout.

Part Context

This component belongs to Mini-Circuits' LTCC filter family, which utilizes low-temperature co-fired ceramic technology for robust performance.
