LFCG-700+

Overview

The Mini-Circuits LFCG-700+ is a miniature low-pass filter utilizing Low Temperature Co-fired Ceramic (LTCC) technology. It provides a DC to 700MHz passband with an 880MHz cutoff frequency. The component operates at a 50 Ohm impedance and features a surface-mount 0805 package measuring 2.00mm x 1.25mm x 1.08mm. Typical specifications include 1.2dB insertion loss, 46dB stopband rejection, and 15dB passband return loss.

Feature Summary

• Miniature LTCC construction for compact surface-mount integration
• Low insertion loss and high stopband rejection characteristics
• Robust design suitable for harsh environments

Applications

• Wireless communication systems
• Test and measurement equipment
• RF signal conditioning circuits

Procurement Notes

Verify the specific ordering suffix required for your packaging preference, such as tape-and-reel or cut-tape options. Confirm RoHS3 compliance status and ensure the selected variant matches the intended PCB footprint dimensions of 0805. Cross-reference the manufacturer part number against distributor listings to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a sharp cutoff near 700MHz is required in a minimal footprint. The LTCC material offers stability compared to other filter types. Ensure the system impedance matches the 50 Ohm specification. Consider the thermal properties of ceramic substrates if operating in high-temperature environments. Verify that the physical size fits within the available board space constraints.

Part Context

This component belongs to the LFCG series from Mini-Circuits, which specializes in miniature RF filters. The series utilizes LTCC technology to achieve high performance in small packages. These filters are designed for applications requiring reliable signal filtering in compact electronic devices. The product line emphasizes consistency and durability for industrial and commercial use cases.

Replacement Considerations

Consult official Mini-Circuits documentation for direct substitutes. Verify electrical compatibility including cutoff frequency and impedance. Check physical package dimensions to ensure mechanical fit on the existing PCB layout.
