Overview
The ARD1004HCQ is a single-pole double-throw (SPDT) RF coaxial switch IC manufactured by Panasonic Electric Works. Designed for cellular applications, it operates with a 50-ohm impedance and supports frequencies up to 18 GHz. The device features a maximum insertion loss of 0.5 dB and provides a minimum isolation of 60 dB at the test frequency. It functions on a 4.5 V supply voltage and is rated for an operating 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 switching configuration for signal routing
- High isolation performance suitable for cellular radio frequency applications
- Operates within extended industrial temperature ranges
Applications
- Cellular phone RF front-end modules
- Wireless communication systems requiring high-frequency switching
- Test and measurement equipment utilizing coaxial interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging and environmental specifications. Confirm that the module package type matches the target PCB footprint design. Check for any recent product change notices regarding availability or material composition updates before finalizing procurement plans.
Selection Notes
Select this component when designing circuits requiring SPDT switching at frequencies up to 18 GHz with low insertion loss. Ensure the system power supply aligns with the 4.5 V requirement. Consider the thermal management capabilities needed to maintain operation within the specified -55°C to 85°C ambient temperature range during continuous use.
Part Context
This part belongs to the ARD series of coaxial switches from Panasonic Electric Works. It serves as a specialized RF component for mobile devices and wireless infrastructure. The HCQ suffix typically denotes specific packaging or quality grades within the broader ARD family, distinguishing it from other variants like ARD10024CQ.
Replacement Considerations
Consult official substitution lists for direct replacements. Verify electrical parameters such as isolation and insertion loss against alternative SPDT RF switches. Ensure mechanical compatibility with the module package and pin contact configuration before considering cross-references.
