The ARD55112C is an RF switch IC designed for cellular applications, manufactured by Panasonic Electric Works. It features a Single Pole Double Throw (SPDT) topology with a nominal operating voltage of 18V DC. The component supports frequencies up to 26.5GHz and operates at 50 Ohms impedance. Key electrical specifications include a minimum isolation of 55dB and a maximum insertion loss of 0.8dB. The device is RoHS compliant and lead-free.
Verify the specific suffix 'Q' against official Panasonic documentation to confirm compliance requirements. Ensure the 18V DC nominal voltage aligns with system design constraints. Confirm package type and pin configuration match PCB layout requirements before ordering.
Select this component for high-frequency cellular applications requiring SPDT functionality. Consider the 26.5GHz frequency range and 50 Ohm impedance for compatibility. Evaluate isolation and insertion loss specs against system performance needs.
The ARD series includes various coaxial switches from Panasonic Electric Works. This model is part of a family offering different frequency ranges and configurations. It is distinct from other series like ARD15124C which may have different operating voltages or frequency limits.
