We describe theoretically the main characteristics of the
steady state regime of a type II Optical Parametric Oscillator (OPO)
containing a birefringent plate. In such a device the signal and
idler waves are at the same time linearly coupled by the plate and
nonlinearly coupled by the 
crystal. This mixed coupling
allows, in some well-defined range of the control parameters,
frequency degenerate operation as well as phase locking between the
signal and idler modes. We describe here a complete model taking
into account all possible effects in the system, i.e. arbitrary rotation
of the waveplate, non perfect phase matching, ring and linear
cavities. This model is able to explain the detailed features of
the experiments performed with this system.
