ADCH-80+

Overview

The ADCH-80+ is a surface-mount RF choke designed for operation between 50 MHz and 10 GHz. It features a 50Ω impedance characteristic and utilizes a CD542 case style with six flat leads. Typical insertion loss ranges from 0.31 dB to 0.38 dB across the lower frequency band, while return loss exceeds 25 dB up to 1 GHz. The component supports high-frequency applications requiring stable impedance and low signal attenuation in microwave circuits.

Feature Summary

• Surface-mount construction for automated assembly
• Wideband operation from 50 MHz to 10 GHz
• Maintains 50Ω system impedance
• Low insertion loss profile

Applications

• RF circuit isolation
• Microwave filter bias networks
• High-frequency signal path blocking

Procurement Notes

Verify the specific suffix designation against the manufacturer's current documentation to confirm exact electrical tolerances and packaging specifications. Ensure the selected variant matches the required impedance and frequency range for the target application. Cross-reference the part number with official Mini-Circuits resources to validate RoHS compliance status and lead times prior to procurement.

Selection Notes

Select this component when a broadband choke is required for frequencies extending into the microwave range. The CD542 package offers a compact footprint suitable for dense PCB layouts. Evaluate insertion loss requirements at the highest operating frequency to ensure signal integrity is maintained within acceptable limits for the specific design.

Part Context

This component belongs to Mini-Circuits' line of surface-mount RF chokes. These components are engineered to provide high impedance to radio frequency signals while allowing DC or low-frequency currents to pass. The series is widely used in communication systems and test equipment where reliable RF isolation is critical.

Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes such as the ADCH-80A. Verify that alternative parts match the 50MHz-10GHz bandwidth and CD542 form factor to maintain board compatibility and electrical performance.
