model variable phase device

libraries:
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.

input

phase — simulink control signal
scalar

simulink control signal, specified as a scalar.

data types: double

parameters

phase shift unit — angle units for controlling phase of circuit
`rad` (default) | `deg`

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

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
on (default) | off

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.

version history

introduced in r2016b

r2021b: variable phase shift block icon updated

starting in r2021b, the variable phase shift block icon is now updated. when you open a model created before r2021b containing a variable phase shift block, the software replaces the block icon with the r2021b version.
