Novel broadband radial curve gradient ridge space power distribution/synthesizer

Abstract

The invention provides a novel broadband radial curve gradient ridge space power distribution / synthesizer. The novel broadband radial curve gradient ridge space power distribution / synthesizer comprises coaxial curve impedance conversion structures, N paths of impedance gradient radial ridge arrays and rectangular waveguide arrays; each path of impedance gradient radial ridges comprise curve impedance gradient structures and gradient rectangular coaxial internal conductors; the rectangular internal conductors are connected with standard coaxial internal conductors, and signal transmission is realized in non-standard rectangular waveguide; electromagnetic signals are input by the standard coaxial internal conductors, then the signals enter an expanded waveguide disk through the curve gradient coaxial internal conductors, and the signals are distributed into N paths of the coaxial internal conductors at the same amplitude and phase by the radial curve gradient ridge arrays and the coaxial conversion structures; the distributed signals are output by the standard coaxial internal conductors for realizing the distribution and syntheses of the N paths of signals. The power distribution / synthesizer is wide in working frequency bandwidth, high in output power, low in power consumption, high in amplitude-phase consistency, large in the number of the power distribution / synthesis paths, compact in structure and convenient to apply.

Description

technical field [0001] The invention relates to the field of microwave and millimeter wave technologies, in particular to a power distribution / combiner. Background technique [0002] With the wide application of microwave and millimeter wave technology in the fields of radar, guidance and satellite communication, the requirements for the bandwidth, gain and output power of microwave and millimeter wave signal sources are getting higher and higher. Microwave and millimeter-wave solid-state power amplifier chips have the advantages of small size, light weight, high reliability, and compact circuit structure, and have become an important part of millimeter-wave radar, guidance, communication, and testing systems. [0003] However, because the output power of a single solid-state device is affected by the physical characteristics of its own semiconductor and the limitations of heat dissipation, processing technology, impedance matching and other issues, it is far from reaching t...

Problems solved by technology

This technical solution can distribute and combine the input signals with equal amplitude and same phase, but limited by the size of the waveguide, it is difficult to apply this solution to the microwave low frequency band, and it is impossible to realize the power distribution and synthesis of multi-channel signals in the microwave frequency band

In addition, the bifurcation of the waveguide and the waveguide is easy to excite high-order modes, which deteriorates the echo reflection at the input port, thus greatly affecting its insertion loss and power combining efficiency.

Therefore, if figure 2 The technical scheme shown also has certain limitations
