The intermittent behavior that can occur in the chaotic systems with the signal filtration near the boundary of the phase chaotic synchronization regime onset is studied. In the framework of the researches carried out we have found that in the system of unidirectionally coupled generators on the tunnel diode the eyelet and ring intermittencies are possible to exist simultaneously near the boundary of the phase chaotic synchronization with the use of the filter with certain parameters.
