Overview
The ARD1004HC is a coaxial RF switch IC manufactured by Panasonic Electric Works, designed for cellular applications. It features a Single Pole Double Throw (SPDT) circuit topology with a 50 Ohm impedance. The device operates up to a test frequency of 18 GHz and requires a coil voltage of 4.5 VDC. Key electrical specifications include a maximum insertion loss of 0.5 dB and a minimum isolation of 60 dB. The component functions within an ambient temperature range of -55°C to +85°C.
Feature Summary
- Provides SPDT switching capability for RF signal routing in cellular systems
- Operates at high frequencies up to 18 GHz with low insertion loss
- Ensures high signal isolation between ports
- Designed for mobile device integration
Applications
- Cellular phone RF front-end modules
- Mobile communication devices requiring signal path switching
- RF testing equipment operating at microwave frequencies
- Wireless infrastructure components
Procurement Notes
Verify the specific suffix variant required for your design, as packaging and availability may differ between standard and tape-and-reel options. Confirm that the 4.5V drive voltage aligns with your system's power supply constraints. Ensure the module package type fits your PCB layout requirements. Check current stock status as lead times can vary significantly based on manufacturer allocation.
Selection Notes
Select this component when designing for cellular applications requiring high-frequency performance up to 18 GHz. The SPDT configuration is suitable for antenna switching or signal path selection. Consider the 50 Ohm impedance match for standard RF traces. Evaluate the thermal management needs given the -55°C to +85°C operating range. Compare insertion loss and isolation specs against system budget requirements.
Part Context
This part belongs to the ARD series of coaxial switches from Panasonic Electric Works. These components are engineered for robust performance in mobile communications. The ARD1004HC specifically targets cellular handsets and related wireless technologies. It represents a specialized solution for managing RF signals in compact electronic devices.
Replacement Considerations
Consult official substitution lists for direct replacements. Verify pinout compatibility and electrical parameters before swapping. Ensure the alternative part supports the same 18 GHz frequency range and SPDT topology.
