LFCN-1575D+

Overview

The LFCN-1575D+ is a low-pass filter from Mini-Circuits designed for RF and microwave applications. It operates with a cutoff frequency of 1575 MHz and maintains a 50 Ohm impedance. The component utilizes LTCC technology and features an SMD/SMT surface mount package in the FV1206 case style. It supports DC pass-through functionality, providing high isolation to ground. The device functions reliably within a temperature range of -55°C to +100°C.

Feature Summary

• LTCC construction for compact surface mount integration
• DC pass-through capability with high ground isolation
• Designed for stable operation across wide industrial temperature ranges

Applications

• S-band upconverter signal conditioning
• RF front-end filtering
• Microwave component assembly

Procurement Notes

Verify the specific suffix designation when ordering, as it defines critical electrical characteristics such as DC continuity. Confirm that the required isolation levels meet system specifications before finalizing procurement. Ensure compatibility with standard SMD reflow processes for the FV1206 footprint. Cross-reference datasheet revisions to confirm parameter stability.

Selection Notes

Select this component when a low-pass filter with DC pass-through is required. The D suffix indicates support for DC IN-OUT connections, distinguishing it from non-DC versions. Consider the 1575 MHz cutoff relative to the target signal bandwidth. Evaluate the FV1206 package size against available PCB real estate constraints.

Part Context

This part belongs to the LFCN series of ceramic filters manufactured by Mini-Circuits. The series offers various cutoff frequencies tailored for different RF bands. The LFCN-1575D+ specifically targets applications requiring filtering around the GPS L1 band or similar S-band frequencies while maintaining DC connectivity.
