R2026bSyntax
Description
add(
adds search parameters to select RF components from a third-party database using one or more
name-value arguments. rfse,'SelectedSearchParameters',Name=Value)
Note
Install the third-party component database containing Analog
Devices™ amplifiers and mixers with the installRFParts()
command.
add(
adds the display columns specified in rfse,'DisplayColumns',displayFields)displayFields to the part
parameter table.
add(
resets the part selection table to display all the columns in it.rfse,'DisplayColumns','all')
Examples
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
amplifierobjects.Choose a specific amplifier that meets your application requirements and create its
amplifierobject.
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 = rfbudget with properties: Elements: [1x3 rf.internal.rfbudget.Element] InputFrequency: 6 GHz AvailableInputPower: -30 dBm SignalBandwidth: 10 MHz Solver: Friis AutoUpdate: true Analysis Results OutputFrequency: (GHz) [ 6 6 6] OutputPower: (dBm) [-10.64 -0.643 -3.975] TransducerGain: (dB) [ 19.36 29.36 26.03] NF: (dB) [ 8.6 8.6 8.6] IIP3: (dBm) [ 8.511 8.511 8.511] OIP3: (dBm) [ 28 38 34.67] SNR: (dB) [ 65.38 65.38 65.37]
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 =

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.
