Model variable phase device
RF Blockset / Circuit Envelope / Elements
The Variable Phase Shift block controls the phase of the output signal of a RF Blockset™ circuit. The block uses a Simulink® signal to control the phase of the circuit. One input terminal is for the Simulink control signal and one input terminal is for the RF Blockset signal.
Phase shifter are commonly used in phased array antenna systems. In these systems, electronically controlled phase shifters steer the antenna beam in space. Phase shifters are also used in test and measurement systems.
Phase shift unit— Angle units for controlling phase of circuit
Angle units for controlling the phase of the signal, specified
rad for radians or
Reference impedances (Ohm)— Reference impedance for phase shifter
50(default) | vector of positive scalars
Reference impedance for phase shifter, specified as a vector of positive scalars.
Ground and hide negative terminals— Ground RF circuit terminals
Select this parameter to ground and hide the negative terminals. To expose the negative terminals, clear this parameter. By exposing these terminals, you can connect them to other parts of your model.
