LFCN-1700+

Overview

The LFCN-1700+ is an LTCC low pass filter designed for frequencies from DC to 1700 MHz. It features a 50Ω impedance and a compact FV1206 surface mount package with dimensions of 0.037 inches (0.94mm) in height. The component exhibits an insertion loss of 1.2dB. It is constructed using temperature-stable ceramic materials and offers excellent power handling capabilities.

Feature Summary

• Utilizes LTCC construction for temperature stability
• Provides high power handling capacity
• Compact surface mount design

Applications

• RF signal filtering
• Harmonic suppression
• Base station equipment

Procurement Notes

Verify the specific suffix requirements, such as 'D' for DC pass-through capability, against the application needs. Confirm the package style matches the PCB layout specifications. Ensure environmental ratings align with operational conditions. Cross-reference electrical parameters with the official datasheet before finalizing procurement decisions.

Selection Notes

Select this component when a low pass filter up to 1700 MHz is required with minimal insertion loss. Consider the FV1206 package size for space-constrained designs. Evaluate the 1.2dB insertion loss against system budget requirements. Check if DC pass-through is needed, which may require the 'D' suffix variant.

Part Context

This part belongs to Mini-Circuits' ceramic filter series, specifically utilizing Low Temperature Co-fired Ceramic technology. It is designed for robust performance in RF applications requiring stable frequency response. The family includes variants with different cutoff frequencies and packaging options to suit diverse circuit requirements.

Replacement Considerations

The LFCN-1700D+ is a confirmed substitute variant offering DC pass-through capability. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement meets the same impedance and power handling requirements.
