HFCG-2500+

Overview

The HFCG-2500+ is a miniature high pass filter utilizing low temperature co-fired ceramic (LTCC) technology. It features a passband from 2.7 to 14.5 GHz with a 50 Ohm impedance. Key electrical specifications include a typical insertion loss of 0.9 dB, a typical return loss of 11 dB, and a stop band rejection of 48 dB. The component operates within a temperature range of -55°C to +125°C and utilizes an 0805 surface mount footprint.

Feature Summary

• Utilizes rugged LTCC construction for minimal performance variation due to parasitics in dense PCB layouts
• Provides high stop band rejection to effectively suppress unwanted lower frequency signals
• Features a compact 0805 surface mount footprint suitable for space-constrained designs

Applications

• RF front-end filtering in communication systems
• Signal conditioning in microwave circuits
• Harmonic suppression in upconverter assemblies

Procurement Notes

Verify the specific datasheet version and parameter tolerances directly with Mini-Circuits or authorized distributors before finalizing design integration. Confirm that the 0805 footprint dimensions align precisely with your PCB layout guidelines. Ensure thermal management strategies account for the specified operating temperature range of -55°C to +125°C during system operation.

Selection Notes

Select this component when a high pass characteristic is required between 2.7 GHz and 14.5 GHz. The LTCC technology offers robustness against environmental stressors compared to other filter types. Consider the 0805 package size if board real estate is limited. Evaluate the 0.9 dB insertion loss against system link budget requirements to ensure signal integrity is maintained across the passband.
