Parallel Coupled Line Filters

Parallel coupled lines cascaded to conform to a filter specification. Common on microstrip and stripline but in such format not much power capacity. For power, then slabline couplers are required(rounded bars). There are spurious harmonics response so either a LPF or suppresion stubs are required.

This is a generic calculation of Zoo and Zoe. A microstrip, stripline or slabline design can be choosen later.
