Calculate directivity of coupler
Directivity of Branchline Coupler
Create a branchline coupler with default values.
coupler = couplerBranchline
coupler = couplerBranchline with properties: PortLineLength: 0.0186 PortLineWidth: 0.0051 SeriesArmLength: 0.0184 SeriesArmWidth: 0.0083 ShuntArmLength: 0.0186 ShuntArmWidth: 0.0051 Height: 0.0016 GroundPlaneWidth: 0.0600 Substrate: [1x1 dielectric] Conductor: [1x1 metal]
Calculate the directivity of the coupler at 2 GHz.
Directivity of Rat-Race Coupler
Create a rat-race coupler with default values.
coupler = couplerRatrace;
Calculate the directivity of the coupler at 3 GHz.
c = directivity(coupler,3e6)
c = -7.3128e-06
coupler — Coupler
Coupler, specified as a coupler object. For a complete list of couplers, see Splitters and Couplers.
frequency — Frequency to calculate directivity
scalar | vector
Frequency to calculate the directivity, specified as an integer in Hz or as a vector with each element specified in Hz.
