ARD5004HC

Overview

The ARD5004HC is a single-pole double-throw (SPDT) RF switch integrated circuit manufactured by Panasonic Electric Works. Designed for high-frequency applications, it operates at a test frequency of 26.5 GHz with a 50 Ohm impedance. The device features a maximum insertion loss of 0.8 dB and provides a minimum isolation of 55 dB. It requires a supply voltage of 4.5 V and functions within a temperature range of -55°C to 85°C. The component is housed in a module package with pin contacts.

Feature Summary

• Single-pole double-throw (SPDT) configuration for signal routing
• Operates at millimeter-wave frequencies up to 26.5 GHz
• Low insertion loss and high isolation characteristics
• Designed for mobile phone and wireless communication systems

Applications

• Mobile phone front-end modules
• Wireless communication base stations
• Test and measurement equipment
• Millimeter-wave radar systems

Procurement Notes

Verify the specific suffix (e.g., HC vs HQ) against the official datasheet to ensure correct packaging and electrical tolerances. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Ensure the 4.5V supply voltage aligns with your system design constraints before procurement.

Selection Notes

Select this component when an SPDT switching solution is required for frequencies near 26.5 GHz. Consider the 50 Ohm impedance match for standard RF transmission lines. Evaluate the thermal performance within the -55°C to 85°C operating range. Compare insertion loss and isolation specs against alternative RF switches if stricter signal integrity is needed. Verify package compatibility with your PCB layout.

Part Context

The ARD5004HC belongs to the ARD series of RF switches from Panasonic Electric Works. This series includes various configurations such as ARD5004HQ and ARD52012C, tailored for different RF applications. These components are typically used in compact electronic devices requiring reliable signal switching at high frequencies. The series supports modern wireless standards demanding low power consumption and small form factors.

Replacement Considerations

The ADJH22024 is listed as a parameter-equivalent substitute by some distributors, though it is a power relay rather than an RF switch; verify functional equivalence carefully. No other direct RF switch replacements are confirmed in the provided documentation. Consult the manufacturer for approved cross-reference lists.
