Re-reading My Microstrip, Matching, Wilkinson, and Branch-Line Work

Question I started with

I placed RFDH concepts beside my actual Cadence coursework screens and separated design equations, entered geometry, and stored markers.

Re-reading My Microstrip, Matching, Wilkinson, and Branch-Line Work — concept flow — I redrew the relationships before returning to the equations.

Connecting the concepts

Effective permittivity and guided wavelength set microstrip length, while matching networks move the load toward the reference impedance. Wilkinson and branch-line circuits both use quarter-wave sections but have different port and isolation mechanisms.

Equations and assumptions

I write the reference impedance, units, and linear-versus-decibel domain before substituting numbers.

l = theta lambda_g / (2 pi)Z_branch = sqrt(2) Z_0 for an equal Wilkinson

Worked example

For Z0=50 ohms, an equal Wilkinson uses 70.71-ohm branches and an ideal 100-ohm isolation resistor. My stored design separately shows tuned values and physical line dimensions.

Re-reading My Microstrip, Matching, Wilkinson, and Branch-Line Work — calculation relationship — This is my explanatory redraw, not an imported RFDH figure or a measurement result.

Connecting it to my coursework and projects

I do not turn the stored 3.7 GHz microstrip marker into exact 3.5 GHz validation. The Wilkinson and branch-line screens remain an existing simulation archive.

What I will check next

Stored screens do not establish phase balance, fabrication tolerance, connector launches, or VNA measurements, and calculator output does not replace those checks.
