Variable Phase Shift

Model variable phase device

  • Library:
  • RF Blockset / Circuit Envelope / Elements

Description

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.

Parameters

expand all

Angle units for controlling the phase of the signal, specified as rad for radians or deg for degrees.

Reference impedance for phase shifter, specified as a vector of positive scalars.

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.

Introduced in R2016b
