HFCN-3800+

Overview

The HFCN-3800+ is a high-pass filter with a center frequency of 7.125 GHz and a cutoff range of 4250 to 10000 MHz. It operates at 50 Ohms impedance in an FV1206-1 surface mount package. The device utilizes low-temperature co-fired ceramic (LTCC) construction, offering hermetic sealing and temperature stability. It supports an operating temperature range from -55°C and handles up to 7W of power.

Feature Summary

• Hermetically sealed LTCC construction for environmental stability
• High power handling capability suitable for demanding RF environments
• Temperature stable performance across specified operating ranges

Applications

• RF signal conditioning in microwave systems
• Frequency filtering in communication transceivers
• Component integration in S-band upconverter assemblies

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct package and termination specifications. Confirm that the required power handling and frequency range align with system design constraints before procurement. Ensure compatibility with standard surface mount assembly processes for the FV1206-1 case style.

Selection Notes

Select this component when a high-power, hermetically sealed high-pass filter is required for microwave applications. The LTCC technology provides robustness against thermal cycling. Consider the 7W power rating and wide bandwidth when designing circuits requiring significant signal attenuation below the cutoff frequency while maintaining passband integrity.

Part Context

This component belongs to Mini-Circuits' HFCN series of LTCC high-pass filters. These filters are designed for ultra-wideband operations ranging from 29GHz to 56.2GHz. The HFCN-3800+ specifically targets the lower end of this spectrum, providing a compact solution for filtering applications in the C and X bands.

Replacement Considerations

Consult official substitution guides for equivalent LTCC high-pass filters. Verify that any alternative part matches the 50 Ohm impedance, FV1206-1 footprint, and 7W power handling requirements. Ensure the replacement maintains the same cutoff frequency characteristics and hermetic sealing standards.
