ARD55105C

Overview

The ARD55105C is a coaxial switch manufactured by Panasonic Electric Works, designed for high-power control applications within a compact form factor. It operates as a Single Pole Double Throw (SPDT) device with two positions and a 50 Ohm impedance. The component supports frequencies up to 26.5 GHz and utilizes a 5 VDC coil voltage. Key electrical specifications include a Voltage Standing Wave Ratio (VSWR) of 1.7, an insertion loss of 0.8 dB, and isolation of 55 dB. It features quick connect terminals with a 3.5 mm pitch.

Feature Summary

• High-frequency operation capability up to 26.5 GHz
• Compact physical size suitable for space-constrained designs
• High power handling capacity for robust signal switching

Applications

• RF signal routing in communication systems
• Test and measurement equipment requiring precise signal path selection
• Microwave circuitry integration

Procurement Notes

Verify the specific datasheet version from Panasonic Electric Works to confirm mechanical dimensions and terminal compatibility. Ensure the 5 VDC coil voltage requirement aligns with your system's power supply capabilities. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Confirm that the quick connect termination type matches your PCB or harness design requirements before finalizing procurement.

Selection Notes

Select this component when a SPDT coaxial switch is required for frequencies approaching 26.5 GHz. The 5 VDC drive voltage makes it suitable for logic-level control interfaces. Consider the 0.8 dB insertion loss and 55 dB isolation metrics for signal integrity requirements. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Evaluate the physical footprint against available board space constraints.

Part Context

This part belongs to the ARD series of coaxial switches from Panasonic Electric Works. The series offers various configurations with different coil voltages and latch/unlatch options. The ARD55105C specifically denotes the 5 VDC coil variant within this family, distinguished by its SPDT configuration and high-frequency performance characteristics compared to lower-speed relay alternatives.

Replacement Considerations

Consult official Panasonic Electric Works documentation for direct cross-references. Verify that any substitute maintains the 26.5 GHz frequency limit, 50 Ohm impedance, and SPDT topology. Ensure coil voltage and terminal types are compatible with existing circuit designs.
