ZHFG-K2500+

Overview

The ZHFG-K2500+ is a 50-ohm high-pass filter utilizing LTCC technology, designed for broadband applications. It operates within a frequency range of 2.7 GHz to 14.5 GHz and features a 2.92mm connector interface. The component typically exhibits an insertion loss of 1.4 dB, a return loss of 15 dB, and stop-band rejection of 55 dB. It supports up to 4 W of RF input power and functions reliably in temperatures as low as -55°C.

Feature Summary

• Constructs a broadband high-pass response using Low-Temperature Co-fired Ceramic (LTCC) technology for stable performance across the specified microwave spectrum.
• Integrates a 2.92mm connectorized package to ensure precise impedance matching and reliable signal transmission in high-frequency environments.
• Provides significant stop-band attenuation to effectively suppress lower-frequency interference while maintaining low insertion loss in the passband.

Applications

• 5G infrastructure and wireless communication systems
• WiFi 6E network equipment
• S-band upconverter assemblies

Procurement Notes

Verify the specific datasheet revision when sourcing, as Mini-Circuits may update electrical tolerances or mechanical drawings over time. Confirm that the 2.92mm mating connectors on adjacent components are compatible with this inline module. Ensure system power levels do not exceed the 4 W rating to prevent thermal damage or performance degradation during operation.

Selection Notes

Select this component when a wide bandwidth from 2.7 GHz to 14.5 GHz is required alongside robust stop-band rejection. The LTCC construction offers durability suitable for demanding test and field conditions. Consider the 2.92mm interface compatibility with existing cabling and fixture setups before integration into the signal chain.
