Design PCB component around particular frequency

Since R2021b



rfpcbcomponent = design(rfpcbobject,frequency) designs a PCB component around the specified frequency.


PCB components designed using the design function operate around the specified frequency with a 10-15% tolerance.

Design an unequal Wilkinson around 1.8 GHz.

uwilk = design(wilkinsonSplitterUnequal,1.8e9);

Plot S-parameters between the frequency range of 0.1 GHz to 6 GHZ.

spar = sparameters(uwilk,linspace(0.1e9,6e9,50))
spar = 
  sparameters with properties:

      Impedance: 50
       NumPorts: 3
     Parameters: [3x3x50 double]
    Frequencies: [50x1 double]


Input Arguments

collapse all

PCB component object, specified as a RF PCB object. For complete list of PCB components, microstrip bends, and traces, see PCB Components Catalog.


The following PCB catalog components are not supported by this function: spiralInductor, interdigitalCapacitor, and stubRadialShunt.

Design frequency of the PCB component, specified as a real positive scalar in hertz.

Example: 3e9

Data Types: double

Output Arguments

collapse all

PCB catalog component operating around specified frequency, returned as a object handle.
