We can custom design and build variable phase shifters to suit your requirements or you can select from our standard products.

variable phase shifter  

PS-13-200 is a 50 Ohm 200W variable phase shifter for use in 13.56MHz RF applications. It enables the user to insert a continuously variable (5 to 180 degrees) phase shift in the signal path.

Basic features include:

•  N type RF connectors
•  Low insertion loss
•  Rated at 200W continuous duty
•   Single knob control


Higher power versions (up to 5kW) are available, these units incorporate Vacuum Variable Capacitors which are ganged together to maintain the “one knob” control. They have a digital readout which indicates the amount of phase shift inserted as the user adjusts the control. A motorized version with a data output option is available for use in process control applications. The higher power level phase shifters are built to order and can incorporate customer unique features if desired.
