LFCN-722+

Overview

The LFCN-722+ is a low-pass ceramic filter manufactured by Mini-Circuits, designed for surface-mount applications. It features a 50 Ohm impedance and operates within a temperature range of -55°C to +100°C. The component utilizes a 4-SMD, No Lead package with dimensions of 0.079" L x 0.049" W (2.01mm x 1.24mm) and a maximum height of 0.041" (1.04mm). Key electrical specifications include a cutoff frequency of 7.94GHz and a typical insertion loss of 3.2dB at +25°C.

Feature Summary

• Utilizes LTCC ceramic technology for high-frequency signal filtering
• Designed for surface-mount assembly on printed circuit boards
• Provides low insertion loss characteristics in the S-band frequency range

Applications

• S-band upconverter designs
• RF signal path filtering
• Microwave communication systems

Procurement Notes

Verify the specific datasheet version and test board configuration (TB-LFCN-722+) when evaluating performance metrics. Confirm that the 4-SMD no-lead package matches your PCB footprint requirements. Ensure operating temperatures remain within the specified -55°C to +100°C range for reliable operation.

Selection Notes

Select this component for applications requiring a compact low-pass filter with a 7.94GHz cutoff frequency. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Consider the small form factor for space-constrained designs while verifying thermal management capabilities for the specified operating temperature range.
