rfdata.network

Store frequency-dependent network parameters

expand all in page

Description

Use the network class to store frequency-dependent S-, Y-, Z-, ABCD-, H-, G-, or T-parameters for a circuit object.

Note

sparameters, yparameters, zparameters, gparameters, hparameters, abcdparameters, and tparameters are recommend over rfdata.network because these objects enable you to calculate S-parameters, Y-parameters, Z-parameters, G-parameters, h-parameters, hybrid g-parameters, ABCD-parameters, and T-parameters for RF data, network, circuit, objects. (since R2023b)

Creation

Syntax

h = rfdata.network
h = rfdata.network('Type',value1,'Freq',value2, Data',value3, 'Z0',value4)

Description

h = rfdata.network returns a data object for the frequency-dependent network parameters h, whose properties all have their default values.

example

h = rfdata.network('Type',value1,'Freq',value2, Data',value3, 'Z0',value4) sets properties using one or more name-value pairs. You can specify multiple name-value pairs. Enclose each property name in a quote

Properties

expand all

Network parameter data, specified as a 2-by-2-by-M array. M is the number of frequencies. The values correspond to the frequencies stored in the 'Freq' property. By default, this property is empty.

Data Types: double

Frequency data , specified as a M-element vector in hertz. The values must be positive and correspond to the order of the IP3 values. By default, this property is empty.

Data Types: double

Type of network parameters, specified as one of the following network parameters:

  • 'S'

  • 'Y'

  • 'Z'

  • 'ABCD'

  • 'H'

  • 'G'

  • 'T'

Data Types: double

Reference impedance, specified as a scalar in ohms. This property is only available when the 'Type' is set to 'S'. The default value is 50 ohms.

Data Types: double

Object name, specified as a 1-by-N character array or string. This is a read-only property.

Data Types: char
