Open end；Thinner cylindrical body is connected with outer conductor 12, is short-circuit end, i.e. open end can regard as low-impedance coaxial transmission
Line, and short-circuit end can be regarded as the coaxial transmission line of high impedance, for lossless transmission line, if its characteristic impedance is ZC, load resistance
Resist for ZL=0, electrical length θ, input impedance are then, then, step impedance resonator is come
It says, as viewed from open end, the high impedance that resonator can be regarded as one section of low impedance coaxial transmission line series connection one section termination short circuit is same
Axis transmission line, wherein the characteristic impedance of high impedance coaxial transmission line is Z1, electrical length θ1, and the spy of low impedance coaxial transmission line
Sign impedance is Z2, electrical length θ2, therefore the input impedance of resonator is, to make required frequency
The power signal transmissions of rate then need the power signal of the frequency along the open end of resonator to short-circuit end to next resonator
The impedance of direction transmission namely ZiIt should be infinitely great, then the condition of resonance of resonator are as follows:, with
The condition of resonance of general uniform impedance resonator uniquely depends on compared with length of transmission line, the step of the step filter 7
