Wilkinson, branchline, ratrace, directional couplers, corporate dividers, Rotman lenses for power splitting and beam-forming. TRIGGER: user asks to design, create, or analyze any coupler, splitter, power divider, combiner, or Rotman lens. Invoke BEFORE writing code — class names and design() availability vary per coupler type. SKIP: EM simulation/S-parameter extraction of an existing component (use matlab-analyze-em), building custom non-catalog geometry (use matlab-assemble-pcb-layout), materia

I have created a 4-port ratrace coupler object in MATLAB. Write a MATLAB expression to numerically evaluate directivity in dB across a frequency array from 3 GHz to 7 GHz without displaying the auto-generated plot.
