Problems solved by technology

It can be seen from the basic working principle of the filter that each independent cavity itself must resonate near a certain frequency point, resulting in the formation of a strong standing wave field in the filter, which greatly reduces the power capacity of the channel and continues to increase the channel The transmission cross-sectional area, the problem of high-order mode competition will inevitably appear, resulting in a sharp decline in the performance of the device in terms of filtering, synthesis, etc.
Therefore, this method must face great design difficulties under the requirements of shorter working wavelength and higher power capacity

Embodiment Construction

[0038] Now take the synthesizing of two channels of different frequency signals at the matching output port and the synthesizing output port of the synthesizer as an example, and illustrate the working mode of the duplex synthesizer in conjunction with the attached drawings:

[0039] figure 2 It is a schematic structural diagram of the quasi-optical dual-frequency synthesizer of this embodiment. It is difficult to achieve high-gain primary radiation only by using a smooth and tapered horn feed. In order to improve the transmission efficiency of the entire duplex combiner, it is necessary to ensure that the input beam has strong quasi-optical characteristics, that is, the beam waist diameter of the input beam is much larger than the operating wavelength. . Therefore, the radiation field of the smooth tapered horn feed needs to pass through two sets of clamshell reflectors to convert the small-aperture Gaussian beam radiated by the horn into a large-aperture Gaussian beam. The...

Abstract

The invention discloses a high-power-capacity quasi-optical double-frequency synthesizer based on an optical interference principle, and belongs to the technical field of microwaves. The quasi-opticaldouble-frequency synthesizer comprises two groups of wide-aperture Gaussian beam exciters, a first beam splitter, a second beam splitter, a first phase reversal mirror, a second phase reversal mirror, a synthesis output port and a matching output port. Transmission wave beams are based on the optical interference principle, and the caliber of a wave beam transmission channel is increased. High-power and high-efficiency transmission of the synthesizer under the condition of large-aperture Gaussian beam quasi-optical transmission is realized.

Description

technical field [0001] The invention belongs to the field of microwave technology, and proposes a quasi-optical dual-frequency synthesizer with high power capacity based on the principle of optical interference. Background technique [0002] High Power Microwave (HPM) has many applications in military and civilian fields such as high-energy particle accelerators, high-power radars, super jammers, high-energy microwave weapons, and high-power microwave sources. Higher demands are placed on the power capacity in these application areas. However, since a single device is limited by its working mechanism, physical limits and processing technology, its radiation power has an upper limit, and power combining technology has become an important technical means to solve the above problems and meet application requirements. [0003] The current international research on HPM power combining technology mainly focuses on two technical approaches, which can be divided into two types: spa...
