Dear Kyle,

There is a behavioral quadrature generator in the rfLibrary called "quadrature" than can generate I and Q phased clocks from its "lead" and "lag" outputs. There is also a phase shifter called "shifter" that accepts an input and generates signals in quadrature that models an RC based phase splitter. As such, its quadrature output amplitudes vary with frequency.

No. You might be able to build one with components in the analogLib, but to my knowledge, there is not a specific behavioral model for a directional coupler in analogLib.
