Abstract :
In this paper, a novel coupling structure with both an iris and a probe is proposed to make it easier to tune negative coupling, because that the total coupling coefficient can be negative and tuning the iris screw would change the coupling coefficient of such mix coupling structure. This coupling structure is applied to a DR filter, the simulated frequency responses are in good agreement with the expectation
