HFCG-3250+

Overview

The HFCG-3250+ is a high-pass filter from Mini-Circuits, operating within the 3.65 to 16.5 GHz frequency range. It features an insertion loss of 0.7 to 2 dB and handles up to 3 W of power. The device offers stop band rejection between 27 and 44 dB, with typical return loss of 11 dB. Constructed using LTCC technology in an SMD package, it provides stable performance for RF signal conditioning.

Feature Summary

• Utilizes LTCC technology for compact surface-mount integration
• Provides high-power handling capability of 3 Watts
• Ensures low insertion loss for efficient signal transmission
• Delivers high stop-band rejection to suppress unwanted frequencies

Applications

• Automotive devices

Procurement Notes

Verify the specific datasheet version and electrical characteristics against the manufacturer's official documentation before procurement. Confirm that the LTCC construction and SMD footprint align with your PCB design requirements. Ensure the 3W power handling and frequency range meet your system's operational needs. Check for any specific environmental ratings or compliance standards required for your application.

Selection Notes

Select this component when a high-pass filter is needed for frequencies above 3.65 GHz. Consider its 3W power rating for applications requiring significant signal handling. The LTCC technology offers stability and compactness suitable for space-constrained designs. Evaluate the insertion loss and rejection specs against your system's noise and interference requirements.
