HFCN-1910+

Overview

The HFCN-1910+ is a ceramic high-pass filter manufactured by Mini-Circuits. It operates within a frequency range of 2200 to 5200 MHz. The component features a 50 Ohm impedance and utilizes low-temperature co-fired ceramic (LTCC) technology. It is housed in a compact 4-SMD, no lead package designed for surface mount applications.

Feature Summary

• Utilizes low-temperature co-fired ceramic construction for stable RF performance
• Designed as a passive high-pass filter with specified rejection characteristics
• Surface mount package optimized for automated PCB assembly

Applications

• RF signal filtering in communication systems
• Frequency selection in upconverter assemblies
• Interference suppression in microwave circuits

Procurement Notes

Verify the specific datasheet version for the HFCN-1910+ to confirm exact electrical parameters such as insertion loss and VSWR. Ensure compatibility with the intended PCB land pattern, referencing layout guidelines like PL-137 if available. Confirm that the operating environment does not introduce DC voltage at ports without appropriate coupling capacitors, or consider suffix variants if required.

Selection Notes

Select this component when a high-pass response starting near 2.2 GHz is required in a small form factor. The LTCC construction offers reliability for mass production. Verify that the power handling capabilities meet system requirements, noting that some sources cite higher power ratings while others focus on linear operation. Ensure the 50 Ohm system impedance matches the surrounding circuitry to minimize reflections.

Part Context

This part belongs to the Mini-Circuits HFCN series of ceramic filters. These components are engineered for ultra-wideband applications ranging from 29 GHz to 56.2 GHz across the broader family. The HFCN-1910+ specifically targets S-band and C-band frequencies, providing a specialized solution within the company's extensive portfolio of RF and microwave passive components.

Replacement Considerations

Check for availability of the HFCN-1910D variant, which may offer different suffix specifications. Verify pinout and footprint compatibility before substituting with other high-pass filters from Mini-Circuits or third-party manufacturers. Ensure equivalent rejection levels at stopband frequencies are maintained.
