ARD5004H

Overview

The ARD5004H is a high-reliability RF coaxial switch manufactured by Panasonic Electric Works, belonging to the ARD series. It features a Single Pole Double Throw (SPDT) topology designed for general RF applications up to 26.5 GHz. The device operates on a 4.5 VDC supply voltage and utilizes solder terminals for mounting. Key electrical specifications include a minimum isolation of 60 dB and a maximum insertion loss of 0.5 dB at the test frequency. It maintains a 50 Ohm impedance and functions within a temperature range of -55°C to 85°C.

Feature Summary

• High reliability RD coaxial switch design
• Fail-safe operation with indicator
• Excellent high-frequency characteristics

Applications

• General RF switching circuits

Procurement Notes

Verify component authenticity through authorized channels. Confirm datasheet revisions match specific lot codes. Check connector heat generation impacts under actual operating conditions as noted in manufacturer remarks. Ensure solder terminal compatibility with assembly processes. Validate availability status as lead times may vary significantly.

Selection Notes

Select this component for applications requiring SPDT switching up to 26.5 GHz. Consider the 4.5V DC drive requirement and module package type. Evaluate thermal management needs due to potential connector heat generation. Compare against other ARD series variants like ARD1004H if lower frequency requirements exist.
