A novel integratable planar T-junction waveguide power divider, a so-called TEH(E-plane input and H-plane output) junction waveguide power divider, with anti-phase outputs and full bandwidth is proposed in this letter. It is basically a E-plane waveguide T-junction with its input port rotated around the axis of the two output ports by 90 degrees to form a planar structure. In order to expand its operation...
An improved structure of rectangular waveguide band-pass filter with harmonic suppression is proposed. The filter consists of cascade resonant cavities with coupling provided by irises. By means of varying the width of each resonator and the offsets between the adjacent resonant cavities, the stop-band was successfully pushed to a two octaves frequency range. The results show that the designed rectangular...
A new structure (patent pending) is introduced to stabilize the frequency drift over temperature variations. The resonator is accurately modeled and calculated, satisfactory temperature compensation is obtained. The computed resonant frequency drift over 100 °C temperature range is less than 10KHz.
This paper presents a filter with resonating-irises and shorting stubs. Each shorting stub not only creates a transmission zero, but also serves as the impedance inverter between adjacent resonating-irises, to form the bandpass filter. Transmission zeros (TZs) at both sides of the passband of a broadband as well as a narrow band filter can be realized. The configuration parameters and simulated results...
