HFCN-103+

Overview

The HFCN-103+ is an LTCC high-pass filter manufactured by Mini-Circuits, designed for RF and microwave applications. It operates within a frequency range of 9700 MHz to 15000 MHz, with a center frequency of 12.35 GHz. The component features a cutoff frequency of 5.3 GHz and maintains a 50 Ohm impedance. Packaged in a compact 1206 (3216 Metric) surface-mount format, it supports board mounting and handles up to 8W of power. The device offers typical rejection of 30 dB and functions reliably across temperatures from -40°C to +85°C.

Feature Summary

• Utilizes LTCC technology for robust construction in a small form factor
• Provides high power handling capability suitable for demanding RF environments
• Delivers high signal rejection characteristics for effective noise suppression

Applications

• RF front-end filtering in communication systems
• Harmonic suppression in microwave circuits
• Signal conditioning in test and measurement equipment

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters and mechanical dimensions. Ensure compatibility with your PCB layout regarding the 1206 package size and thermal requirements. Cross-reference part numbers to avoid confusion with similar series components. Confirm operational temperature ranges match your system environment before integration.

Selection Notes

Select this component when a high-pass filter is required for frequencies above 5.3 GHz. Consider its 8W power handling if driving high-power signals. The LTCC construction suits applications needing durability and consistent performance. Evaluate the 1206 footprint against available board space constraints.
