Embodiment Construction
[0025] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0026] see figure 1 , in the schematic diagram of the assembly structure of the first embodiment of the elliptic function type high-pass filter channel of the present invention, the high-pass filter channel is designed and formed in a metal cavity 2, mainly including a longitudinal cavity formed in the metal cavity 2 20. Two connection ports 31, 32 located on both sides of the cavity 20 in the longitudinal direction and fixed on the cavity wall of the metal cavity 2, and arranged linearly along the longitudinal direction of the cavity 20 and sequentially capacitively coupled to form A plurality of conductor rods 4 of the capacitor connected in series, the conductor rods 4 located at both ends of the cavity 20 in the longitudinal direction are capacitively coupled with the inner conductors 310, 320 of the two connection ports 31, 32 respectively, so as to real...
