At first, path filter should design passband return loss and the belt resistance inhibitor system that reaches more excellent; Secondly, two path filters are with after T junction is connected, variation has taken place in the phase place of reflection coefficient, at this moment need be at inner tuning tooth and the diaphragm of increasing of T junction, as shown in Figure 7, by shape, the position that changes tuning tooth and diaphragm, adjust the waveguide length of junction, come the variation of compensatory reflex coefficient phase place.Because influencing each other between these tuning links is complicated, variable need be arranged to optimize in their size, position, the passband return loss and the stopband of frequency diplexer are suppressed to be arranged to optimization aim, be optimized, realize the Broadband Matching of frequency diplexer by pattern matching method.
(2) high power tolerance
Because filter adopts the resonant cavity form, signal produces resonance at resonant cavity, and the electric current additive effect is very big, therefore adopts H facial mask sheet filter shown in Figure 7, makes that the distance of waveguide internal electric field transmission is maximum, to improve its micro discharge surplus; Thermal field according to frequency diplexer distributes simultaneously, at the Position Design fin of thermal field fastest transmission, as shown in Figure 6, can reduce the parts surface temperature, protects its operate as normal.
(3) anti-PIM design
Frequency diplexer makes mismachining tolerance reach minimum to the influence of electrical property by fully optimizing and tolerance analysis, does not therefore have any adjustable link, avoids the PIM that causes because of discontinuity; Adopt broadside symmetry subdivision (position as shown in Figure 6), first contains public port, and second shell one side has and the parallel fin in the narrow limit of filter, and the inside diaphragm of two halves adopts integrated processing.The split surface current density is minimum, can avoid the non-linear contact-making surface electric current that causes of electric field to increase sharply; The path filter diaphragm adopts integrated processing mode, does not have welding technology, avoids the non-linear generation PIM because of material.
Testing experiment result of the present invention is as follows:
