LFCW-8700+

Overview

The Mini-Circuits LFCW-8700+ is a ceramic low-pass filter utilizing LTCC technology. It provides a passband from DC to 8.7 GHz with a cutoff frequency of 10.1 GHz. The component operates within a 50Ω system and features a JC0603C-1 case style, corresponding to the 0603 (1608 Metric) surface-mount package. Electrical performance includes a typical insertion loss of 2.3 dB. The device supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) construction for robust signal filtering
• Provides high isolation in the stopband beyond the 8.7 GHz cutoff frequency
• Designed for compact integration via standard 0603 surface-mount footprint

Applications

• RF front-end filtering in wireless communication systems
• Signal conditioning in microwave measurement equipment
• Harmonic suppression in RF signal generation circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct termination and packaging specifications. Confirm that the JC0603C-1 case style matches the intended PCB layout requirements. Cross-reference the datasheet revision date to validate the accuracy of the provided electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when a sharp cutoff near 8.7 GHz is required within a 50Ω environment. The wide operating temperature range makes it suitable for demanding industrial or military applications. Ensure the design accommodates the physical dimensions of the 0603 package and accounts for the specified insertion loss in the link budget calculations.

Part Context

This part belongs to the LFCW series of ceramic low-pass filters manufactured by Mini-Circuits. These components are engineered for high reliability and consistent performance across a broad frequency spectrum. The series utilizes advanced LTCC processes to achieve stable electrical characteristics in compact form factors suitable for modern electronic designs.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify that any replacement maintains the same cutoff frequency, impedance, and package dimensions to ensure circuit compatibility without redesign.
