ARD25112Q

Overview

The Panasonic Electric Works ARD25112Q is an active RF coaxial switch from the ARD series, designed for high-frequency applications up to 18 GHz. It features a Single-Pole Double-Throw (SPDT) configuration with a nominal operating voltage of 13V DC. The device maintains a 50 Ohm impedance and exhibits a maximum insertion loss of 0.5 dB. Constructed as a surface-mount component in a box package, it supports cellular RF signal routing with low power consumption and fast switching speeds suitable for modern wireless infrastructure.

Feature Summary

• High-frequency operation capability extending up to 18 GHz
• Single-Pole Double-Throw (SPDT) switching topology
• Low insertion loss characteristic of 0.5 dB maximum
• Surface-mount packaging for automated assembly integration

Applications

• Cellular base station antenna switching
• RF test and measurement equipment signal routing
• Wireless communication system front-end modules
• Satellite communication ground stations

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required voltage levels and pin configurations. Confirm that the surface-mount footprint matches the design board layout. Request the latest RoHS compliance documentation and material safety data sheets prior to final procurement approval to meet regulatory standards.

Selection Notes

Select this component when an SPDT switch is required for frequencies up to 18 GHz with strict insertion loss constraints. Ensure the system design accommodates the 13V DC nominal operating voltage. Consider the thermal management requirements associated with the surface-mount package type and verify that the 50 Ohm impedance aligns with the surrounding RF circuitry.

Part Context

This part belongs to the Panasonic ARD series of coaxial switches, which includes variants such as ARD25112, ARD65112, and ARD25124. These components are engineered for robust performance in demanding RF environments. The ARD25112Q specifically addresses the need for reliable signal path switching in compact form factors used in advanced telecommunications hardware.

Replacement Considerations

Direct substitutes within the same family include ARD25112, ARD65112, ARD25124, and ARD65124. Verify electrical parameters and pinout compatibility before substitution. Cross-reference with other manufacturers' SPDT switches rated for 18 GHz if Panasonic supply is unavailable.
