Coupled Line Propagation

Coupled Line Propagation:

Wave equations for coupled lines, propagation models, coupled line parameters, coupled line parameter variations with frequency, directional couplings, Lange coupler coupled line pair treated as a four port, coupled line pair operated as a two port assuming Oe = 0o, low pass filtel design assuming Oe =0o, coupled line pair analyzed to a two port Oe not equal to 0o, narrow band filter using coupled resonator, narrow band coupled line filters, suspended substrate strip lined filters, suspended substrate strip line filter design using method 1 and method 2.
