Procurement Notes

Verify the specific datasheet version for the ZHFG-K3250+ to ensure compatibility with your system requirements. Confirm that the connector type and impedance match your existing infrastructure. Check for any RoHS compliance documentation if required for your manufacturing process. Ensure that the operating temperature range aligns with your environmental conditions. Always refer to the manufacturer's official specifications for final validation before integration.

Selection Notes

Select the ZHFG-K3250+ when a high-pass filter with a cutoff near 3.25 GHz is needed. Consider its LTCC construction for durability and consistent performance. Evaluate the typical insertion loss and return loss against your system's sensitivity requirements. Ensure the 50-ohm impedance matches your circuit design. Verify that the frequency range up to 16.5 GHz covers your operational bandwidth needs.

Part Context

This component belongs to Mini-Circuits' ZHFG series of high-pass filters. These filters are known for their compact size and reliable performance in RF applications. The ZHFG-K3250+ specifically targets frequencies above 3.65 GHz, making it suitable for S-band and higher frequency applications.
