ARD15112Q

Overview

The ARD15112Q is a latching RF coaxial relay module manufactured by Panasonic Electric Works. It features a single-pole double-throw (SPDT) configuration with a 50 Ohm impedance and operates on a 12V DC supply. The device supports frequencies up to 18 GHz, with a maximum input power of 120 W. Key electrical specifications include a maximum insertion loss of 0.5 dB and isolation of 60 dB. It utilizes TTL driver latching with an indicator and offers a mechanical life of 5,000,000 cycles. The unit is housed in a module package with pin contacts and functions within a temperature range of -55°C to 85°C.

Procurement Notes

Verify the specific suffix 'Q' against official Panasonic documentation to confirm RoHS compliance status and exact material composition. Ensure the TTL driver requirement matches your control logic voltage levels. Confirm that the 12V coil specification aligns with your system power supply capabilities before finalizing procurement orders.

Selection Notes

Select this component when a latching mechanism is required to maintain state without continuous power consumption. The SPDT topology suits simple signal path switching needs. Consider the 18 GHz frequency limit and 120 W power handling to ensure compatibility with your RF chain requirements. Verify interface compatibility with existing TTL control circuits.

Part Context

This part belongs to the ARD series of RF coaxial relays from Panasonic Electric Works. These modules are designed for high-reliability switching applications requiring low insertion loss and high isolation. The series typically includes various pole configurations and frequency ranges, with the ARD15112Q specifically offering SPDT functionality optimized for microwave frequencies.

Replacement Considerations

Consult official Panasonic substitution guides for verified equivalents. Cross-reference impedance, frequency limits, and latching type when evaluating alternatives. Ensure any substitute maintains the 12V DC coil requirement and compatible physical mounting dimensions.
