HFCN-880D+

Overview

The HFCN-880D+ is a low-temperature co-fired ceramic (LTCC) high-pass filter manufactured by Mini-Circuits. It operates within a frequency range of 950 MHz to 3200 MHz, with a center frequency of 2.075 GHz and a bandwidth of 2250 MHz. The component features a 50 Ohm impedance and utilizes an SMD/SMT termination style in the FV1206 case package. It contains seven sections and offers a minimum DC resistance to ground of 100 Mohms.

Feature Summary

• Constructed using low-temperature co-fired ceramic (LTCC) technology for robust performance
• Designed as a high-pass filter to attenuate frequencies below the cutoff point
• Utilizes surface-mount device (SMD) termination for automated assembly compatibility

Applications

• RF signal conditioning in communication systems
• Interstage filtering in upconverter assemblies
• Noise suppression in microwave circuits

Procurement Notes

Verify the specific suffix 'D+' against the manufacturer's current datasheet to confirm pinout and tolerance specifications. Ensure the ordering part number matches the required LTCC variant. Confirm that the FV1206 footprint aligns with the target PCB design. Validate that the 50 Ohm impedance meets system requirements before procurement.

Selection Notes

Select this component when a high-pass characteristic is required between 950 MHz and 3200 MHz. The LTCC construction suits applications demanding stable thermal performance. The SMD format facilitates integration into compact RF modules. Verify that the insertion loss and rejection levels at the datasheet-specified test board conditions meet the system link budget.

Part Context

This component belongs to the Mini-Circuits HFCN series of LTCC high-pass filters. These components are engineered for ultra-wideband applications, often serving as critical filtering elements in complex RF assemblies such as upconverters and mixers. The series provides reliable attenuation of unwanted lower-frequency signals while passing desired higher-frequency bands.

Replacement Considerations

Consult official substitution guides for compatible LTCC high-pass filters with matching 950-3200 MHz ranges and FV1206 footprints. Verify electrical equivalence regarding center frequency and impedance before swapping.
