Overview
The ARD55124CQ is a coaxial RF switch manufactured by Panasonic Electric Works, designed for cellular applications. It operates as an SPDT switch with a nominal impedance of 50 Ohms and supports frequencies up to 26.5GHz. The device features a latching operating function controlled by a TTL driver and includes an integrated indicator. It requires a supply voltage of 24V DC. The component is supplied in a box package and is currently active in production.
Feature Summary
- Coaxial RF switch architecture optimized for cellular communication systems
- Single Pole Double Throw (SPDT) configuration with 50 Ohm impedance
- Latching operation mode driven by TTL logic signals
- Integrated status indicator for visual operational feedback
Applications
- Cellular base station front-end modules
- RF signal routing in wireless infrastructure equipment
- Test and measurement instrumentation requiring high-frequency switching
- Mobile device prototyping and development kits
Procurement Notes
Verify the specific datasheet version when ordering, as the manufacturer distinguishes between models with and without attached HF datasheets. Confirm that the required TTL driver interface matches the system design. Ensure the 24V DC supply voltage aligns with the power management circuitry. Check for RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this component when a latching RF switch is required for cellular frequency bands up to 26.5GHz. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Consider the TTL driver requirement for control logic integration. Evaluate the physical package constraints against the PCB layout requirements for the specific application environment.
Part Context
This part belongs to the ARD series of coaxial switches from Panasonic Electric Works. The series includes variants such as ARD55124C and ARD55112CQ, which may differ in frequency specifications or documentation availability. The ARD55124CQ specifically targets the 26.5GHz performance class within this product family.
Replacement Considerations
Direct substitutes are not explicitly confirmed in public documentation. Verify compatibility with existing TTL control signals and 24V supply requirements before replacing. Cross-reference impedance and frequency limits with alternative RF switches to ensure signal integrity is maintained in the target application.
