    Syntax

    remove(rfse,'SelectedSearchParameters',Name=Value)
    remove(rfse,'DisplayColumns',displayFields)
    remove(rfse,'SelectedSearchParameters','all')

    Description

    remove(rfse,'SelectedSearchParameters',Name=Value) removes search parameters to select RF components from a third-party database using one or more name-value arguments.

    Note

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

    remove(rfse,'DisplayColumns',displayFields) removes the display columns specified in displayFields to the part parameter table.

    example

    remove(rfse,'SelectedSearchParameters','all') rests all the selected search parameters.

    Examples

    Open Live Script

    Install the third-party component database.

    installRFParts()

    First, create an rfPartSelector object to specify the type of component you want to select. 

    rfps = rfPartSelector(Type='amplifier',Vendor='ADI')

    Display all the available amplifier components from the database.

    show(rfps,'all')

    The installed database contains 174 amplifiers. Add filters to select amplifiers that operate with 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. For this example, remove five parameters.

    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 objects. For this example, create an amplifier object for the first amplifier in the table. 

    amp = rfPart(rfps,1)

    Compute the S-parameters of the selected amplifier and plots its characteristics. 

    spar = sparameters(amp,linspace(4e9,20e9,101));
rfplot(spar);

    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: add(rfse,'SelectedSearchParameters',Frequency=2000,RFPrimaryFunction='VGA')

    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: PartNumber='ADL5240AMP'

    Component application, specified as a character vector. The value you specify in RFPrimaryFunction must match with a application in the installed database. To display the component applications of all parts in the installed third-party database, see the show function.

    Example: RFPrimaryFunction='VGA'
