phaseshift

Creates a phase-shifting circuit.

Library

EngeeRF

Syntax

Function call

psh = phaseshift() — creates a phase-shifting circuit object whose properties are set by default.

psh = phaseshift(Name=Value) — creates a phase-shifting chain object with properties specified by one or more arguments of the type Name=Value. Unspecified properties retain their by default values.

Arguments

Name-value input arguments

# Name — name of the phase-shifting circuit

+ "phaseshift" (by default) | string

Details

The name of the phase-shifting circuit. All names must be valid variable names.

Типы данных

String

# PhaseShift — phase shift, deg.

+ 90 (by default) | positive scalar

Details

The phase difference between the input and output signals in degrees, expressed in terms of the phase shift introduced by the circuit elements, given as a positive scalar.

Типы данных

Float64

# NumPorts — number of ports

+ 2 (by default) | scalar

Details

The number of ports specified as an integer scalar.

This argument is read-only.

Типы данных

Int64

# Terminals — terminal names

+ ("p1+", "p2+", "p1−", "p2−") (by default) | tuple of strings

Details

Terminal names specified as a tuple of strings.

This argument is read-only.

Output arguments

# psh — the object of the phase-shifting circuit

+ object

Details

The object of the phase-shifting circuit.

Examples

Creating a phase-shifting circuit object with by default properties

Details

Create a phase-shifting circuit object and display its properties.

using EngeeRF

psh = phaseshift()


println("Name: ", psh.Name)
println("PhaseShift: ", psh.PhaseShift)
println("NumPorts: ", psh.NumPorts)
println("Terminals: ", psh.Terminals)

Name: phaseshift
PhaseShift: 90.0
NumPorts: 2
Terminals: ("p1+", "p2+", "p1-", "p2-")

Creation of a phase-shifting circuit and calculation of S-parameters

Details

Let’s create a circuit with a phase shift by 25 degrees for the radio receiver and calculate the S-parameters at the frequency 3 GHz.

using EngeeRF

psh = phaseshift(PhaseShift = 25)
spar = sparameters(psh,3e9)

sparameters(Impedance = 50.0, NumPorts = 2, Parameters = ComplexF64[0.0 + 0.0im 0.9063077870366499 + 0.42261826174069944im; 0.9063077870366499 + 0.42261826174069944im 0.0 + 0.0im;;;], Frequencies = [3.0e9])
