HFCG-2000+

Overview

The HFCG-2000+ is an LTCC high-pass filter with a passband from 2100 MHz to 10000 MHz. It features a cutoff frequency of 1930 MHz and operates up to 10 GHz. The component exhibits typical insertion loss of 0.9 dB and return loss of 11 dB in the passband, with stopband rejection of 49 dB. It utilizes a compact 0805 (2.0 mm x 1.25 mm) surface-mount package designed for reliable RF filtering applications.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for robust performance
• Provides accurate cutoff characteristics at 1930 MHz for dependable signal filtering
• Offers low insertion loss of 0.9 dB typical within the operating passband

Applications

• RF and microwave signal processing
• Frequency conversion circuits
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet revision when sourcing, as Mini-Circuits may update electrical specifications or mechanical drawings over time. Confirm that the 0805 footprint matches your PCB design constraints. Ensure the voltage rating and power handling capabilities align with your system requirements before finalizing procurement.

Selection Notes

Select this component when a sharp high-pass response is required above 2.1 GHz with minimal signal attenuation. The small 0805 form factor makes it suitable for space-constrained designs. Consider the 49 dB stopband rejection if strong out-of-band interference suppression is necessary below the cutoff frequency.

Part Context

This part belongs to Mini-Circuits' HFCG series of LTCC filters, which are engineered for high reliability in demanding RF environments. The series covers various cutoff frequencies, allowing designers to tailor frequency responses without sacrificing board real estate. These components bridge the gap between discrete LC filters and larger ceramic resonators.

Replacement Considerations

The HFCG-2200+ is a documented substitute within the same family, offering similar LTCC construction but with a different cutoff frequency. Verify that the alternative's passband and rejection characteristics meet the specific circuit requirements before substitution.
