HFCG-3500+

Overview

The HFCG-3500+ is a miniature low temperature co-fired ceramic (LTCC) high pass filter manufactured by Mini-Circuits. It operates within a frequency range of 3900 to 16500 MHz and features a center frequency of 10.2 GHz. The component is designed for surface mount installation in a GE0805C-9 case style, measuring 0.126 inches in length, 0.063 inches in width, and 0.042 inches in maximum height. It maintains a system impedance of 50 ohms.

Feature Summary

• Constructed using low temperature co-fired ceramic (LTCC) technology for rugged performance
• Designed for dense PCB layouts with minimal performance variation due to parasitics

Applications

• RF signal conditioning in microwave circuits
• Integration into compact RF front-end modules
• High-frequency filtering in communication systems

Procurement Notes

Verify the specific LTCC construction details and electrical specifications against the official Mini-Circuits datasheet prior to integration. Confirm that the GE0805C-9 package dimensions align with the target PCB footprint. Ensure compatibility with the required 50-ohm system impedance and operating frequency range of 3900 to 16500 MHz for the intended application environment.

Selection Notes

Select this component when a robust, miniature high-pass filter is required for frequencies between 3900 and 16500 MHz. The LTCC construction offers durability suitable for demanding environments. Consider the GE0805C-9 surface mount package for space-constrained designs where parasitic effects must be minimized during assembly.

Part Context

This component belongs to the HFCG series of LTCC high-pass filters from Mini-Circuits. These filters are engineered for RF and microwave applications, providing reliable signal filtering in a compact form factor. The series is known for its stability and suitability for modern electronic designs requiring high-frequency performance.

Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes within the HFCG series or other compatible LTCC high-pass filters. Verify that any alternative part matches the 3900-16500 MHz range and 50-ohm impedance requirements.
