rfPart

R2026b

Create RF component from selected third-party components

Since R2026a

Syntax

rfPart(rfse)

rfPart(rfse,partNumber)

rfPart(rfse,listNumber)

rfp= rfPart(___)

rfp = rfPart(rfse,partNumber,Name=Value)

Description

rfPart(rfse) creates RF components from the third-party components selected in rfse. Select components from the installed 3P component database using the rfPartSelector object.

Note

Install the third-party component database containing Analog Devices™ amplifiers and mixers with the installRFParts() command.

rfPart(rfse,partNumber) creates an RF component using part number of a third-party component specified in partNumber.

rfPart(rfse,listNumber) creates an RF component using the list number of a third-party component specified in listNumber.

rfp= rfPart(___) returns an amplifier, modulator, or mixerIMT object using any of the input argument combinations in the previous syntaxes.

rfp = rfPart(rfse,partNumber,Name=Value) returns a modulator or mixerIMT object using the ConverterType, ModelType, and Sideband name-value arguments. Use this syntax when you set the Type property of the rfPartSelector object to mixer. For example, rfPart(rfse,"HMC8191LC4",ConverterType="DownConverter",ModelType="IMT",Sideband="LSB") returns a mixerIMT object created from the lower-sideband HMC8191LC4 mixer.

Note

For this syntax, you must specify all three name-value arguments: ConverterType, ModelType, and Sideband.

Examples

Create Amplifier from 3P Component

Install the 3P component installed database.

installRFParts()

Select the amplifier from the 3P component installed database. To do this, first create an rfPartSelector object to specify the type of component you want to select.

rfps = rfPartSelector(Type='Amplifier')

Display all the available amplifier components from this database.

show(rfps,'all')

The installed database contains 174 amplifiers. Add parameter filters to select the amplifiers that operates with the gain between 12 dB and 20 dB, noise figure between 4 dB and 10 dB, OP1 between 20 dBm and 30 dBm, and OIP3 between 20 dBm to 30 dBm.

add(rfps,"SelectedSearchParameters","GainRange",[12 20], "NoiseFigureRange",[4 10],"OP1dBRange",[20 30],"OIP3Range",[20 30])

Display the selected amplifiers.

show(rfps,'selected')

The part parameter table contains 14 columns. Retain only the columns that are relevant to your search criteria. In this example, five parameters are non-relevant and must be removed from the table.

remove(rfps,"DisplayColumns","OPSAT (dBm)","Voltage (V)", "Current (mA)", "Operating Temp (degC)","Package Type")

Display the selected amplifiers with the updated part parameter table.

show(rfps,'selected')

Use the rfPart function to create amplifiers from 3P component data. You can either:

• Select all amplifiers displayed based on your filtering criteria and generate amplifier objects.

• Choose a specific amplifier that meets your application requirements and create its amplifier object.

amp = rfPart(rfps,"HMC451LP3")

Build an RF chain that includes this amplifier, a component modeled from a Touchstone file, and an element created using an rfelement object. Then, calculate the RF budget for the complete chain at an input frequency of 6.09 GHz, an available input power of −30 dBm, and a bandwidth of 10 MHz.

n = nport('passive.s2p');
r = rfelement(Gain=10);
b = rfbudget([amp r n],6.09e9,-30,10e6)

The RF budget result as follows:

b =

Select Mixer From Component Database

Use the rfPartSelector object to search and filter mixer components from the Analog Devices database, then create an RF mixer component from the results.

First, install the third-party component database.

installRFParts()

Create an rfPartSelector object for mixers from Analog Devices.

rfse = rfPartSelector(Type="mixer", Vendor="ADI")

rfse = 
  rfPartSelector with properties:

                        Type: "mixer"
                      Vendor: "ADI"
            SearchParameters: {16×1 cell}
    SelectedSearchParameters: {}
             ParameterValues: {}
                 NumAllParts: 82
            NumSelectedParts: 82
              DisplayColumns: {14×1 cell}

Filter for downconverter IQ mixers with conversion gain between -9 and -6 dB.

add(rfse, "SelectedSearchParameters", ...
    "ConverterType", "DownConverter", ...
    "GainRange", [-9 -6], ...
    "RFPrimaryFunction", "IQ Mixer")

Display the filtered mixer parts in a table.

rfse — RF part selector

rfPartSelector

RF part selector, specified as an rfPartSelector object.

partNumber — Part number of 3P component

string

Part number of a third-party component, specified as a string. The value you specify in PartNumber must match with a part number in the installed database. To display the part numbers of all parts in the installed third-party database, use the show function.

Example: [1 3 6 13]

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: rfPart(rfse,"HMC8191LC4",ConverterType="DownConverter",ModelType="IMT",Sideband="LSB")

ConverterType — Converter type of mixer

UpConverter | DownConverter

Converter type of the mixer, specified as either UpConverter or DownConverter.

Example: ConverterType="UpConverter"

ModelType — Model type of mixer

IMT | Non Linear

Model type of the mixer, specified as either IMT or Non Linear.

Example: ModelType="IMT"

Sideband — Sideband of mixer

LSB | USB

Sideband of the mixer, specified as either LSB or USB.

Example: Sideband="LSB"

Output Arguments

rfp — RF component

amplifier object | modulator object | mixerIMT object

RF component, returned as an amplifier, modulator, or mixerIMT object, or as an array of these objects.

Version History

Introduced in R2026a

R2026b: Create mixer objects from third-party components

You can now use the rfPart function with the ConverterType, ModelType, and Sideband name-value arguments to create a modulator or mixerIMT object from the Analog Devices component database.
