HFCG-1100+

Overview

The HFCG-1100+ is a miniature low temperature co-fired ceramic (LTCC) high pass filter manufactured by Mini-Circuits. It operates within a frequency range of 1400 to 3900 MHz. The component features a cut-off frequency of 1100 MHz and maintains a system impedance of 50 ohms. It exhibits a maximum insertion loss of 2.5 dB in the passband. The device is housed in an SMD package with dimensions of 2x1.2 mm, utilizing an eight-pin configuration. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Constructed using eleven-layer LTCC technology for high performance repeatability
• Wrap-around electrode design enables miniature surface-mount footprint
• Robust thermal stability across industrial temperature ranges

Applications

• S-band upconverter signal conditioning
• RF front-end filtering in communication systems
• Microwave circuit integration requiring compact form factors

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters and mechanical drawings. Ensure compatibility with standard reflow soldering profiles for LTCC components. Confirm that the 50-ohm impedance matches the surrounding circuit design requirements before integration into the final assembly.

Selection Notes

Select this component when a high-pass filter with a 1100 MHz cutoff is required in a space-constrained application. The LTCC construction offers superior reliability compared to discrete lumped element designs. Consider the 2x1.2 mm package size for dense PCB layouts where traditional through-hole or larger SMD filters cannot fit.

Part Context

This part belongs to the HFCG series of LTCC high pass filters from Mini-Circuits. The series utilizes multi-layer ceramic technology to achieve miniaturization while maintaining consistent RF performance. These filters are designed for use in RF, IF, and microwave applications ranging from DC to higher frequency bands.
