Abstract

The present invention relates to an UHF filter that comprises a dual-mode resonator formed on a wave-guide having a round cross-section. The input connection member (1) and the output connection member (2) consist of oval openings which are connected respectively to input and output connection lines (3, 4), wherein said lines are made in the form of two rectangular wave-guides. The filter also includes two members (5, 6) in the form of screws for adjusting the resonance frequencies with two types of oscillation. The input and output connection members (1, 2) are arranged at an angle of approximately 90° relative to each other and at an angle of 45° relative to the members (5, 6) for adjusting the resonance frequencies, wherein said members (5, 6) are in turn arranged at an angle of approximately 90° relative to each other. The resonators of the UHF filter are tuned at various resonance frequencies.

The supply filter φ 4167713 contains two components that are equipped with a number of filter links in a single common external box that is compatible with other

30 vibrations, input and output communication elements connected to connecting lines, and two elements of regulating the external frequency of each type of disturbance.

The cost of this technical solution is a significant weakening, such as a filter in the area

35% of the load, a high level of unevenness of the load in the bandwidth of the filter, as well as a slight loss of service

This drawback is due to a cascading connection

Through the input connecting line 3 and the input element

5 connection 1 in the output (Fig. 1), the electric energy is released in the form of vibrations with an electric component of the Hex. Perpendicular input - an integral element of communication 1. Electric component of the vibration of the Hex. may be provided in the form of two mutually shared synonymous

10 regards Ε1 and Ε2. The outgoing frequency of the outlet for the type of disruption Ε1 is regulated by the element 5 of the regulation of the unsettled frequency, and for the occurrence of the frequency of Ε2 there is no element

20 Therefore, the output connection element 2 and the subsequent connecting line 4 will be excited by the components of the vibrations ΕΙ.1 and Ε2.1 (fig. З). Electromagnetic oscillations ΕΙ.1 and .12.1 are directed to the convenient parts, which are in connection with the difference of frequency Ρ1 and Ρ2 of the two oscillations

25 The operator is responsible for the excitation of the outgoing element 2 of the connection with vibrations of equal amplitude. Moreover, the vibrations of V.1 and V2.1 completely mutually compensate for the friendship of the friends and do not cause any energy transmission through the SSC filter. The transmission factor is zero at any rate,

If there is a difference in the frequency of the disturbance of the second type, the two types of disturbance of the patient are found to be at risk of the second

35 amplitude-frequency characteristics away from the non-resonant parts and Ρ2 in areas I and III (Fig. 4.2). These properties of the proposed filter may be explained using the equivalent circuit (Fig. 2.3), where the filter outputs are connected as a trace

40 kompleksnyx с1 and Ζ2 gears. It should be noted that, in spite of the fact that the resonant parts Ρ1 and Ρ2 are of the value of the complex components Ζ1 and Ζ2 are equal to the module, they are also important. Equivalent power supply of the filter in total equal to the sum of the complex components Ζ1 and Ζ2 and will be equal to zero

45 at any rate that complies with the short circuit mode - 5 - and the complete lack of power transmission to the output connecting line 4.

10th value gives the value for the module more than each of the folded elements. With this transmitting factor, the offer of the filter will be higher than the transmitting factor of any individual switch (1 or 2).

15 Regions I, the complex components Ζ1 and Ζ2 are purely inductive and small, and in the case of complex, they are small and have a small value.

The phrasing characteristic (Fig. 4.3) shows that,

20 attacking mobile components Ζ1 and Ζ2, are turned on a friend of the other friend on an angle close to 180 ° in areas I and III. Keeping track of such small, close to module and almost convenient directions, in addition to the separation of the equivalent of the operation of the filter

25, the value is substantially smaller than any of the summed values, which explains the sharp decrease in the transmission coefficient of the RHF filter in the case of the I and III transmission losses (of the transmission medium 2).

30 For the reasoning above, it has been argued that the proposed RNF filter will have a high linearity in phase-frequency characteristics, i.e. low latency of the group of lagging time (LNG), small insignificant losses in the bandwidth

Researches of frequent characteristics of small mock-ups offered by the R&D filaments showed the following results (Fig. 4.2):

1. The area I is in good condition with a quick offer of 25 RMS is equal to the speed in a non-analogous circuit

2. Region II Relaxation, as proposed by the RISK FIELD in the area of descent, is by two times
