Embodiment Construction

[0019] The present invention will now be further described in conjunction with the embodiments and drawings:

[0020] The purpose of a passive power combining network with a waveguide-dual-pair fin line-microstrip line transition structure in the radar transmitter is to achieve power combining in the waveguide, ensuring good power combining efficiency and working bandwidth, and a small Radiation loss, and is suitable for the installation of solid-state devices in microstrip printed circuits. In the present invention, regular rectangular standard waveguides are used as power input and output ports. In terms of physical structure, the broad side of the waveguide can be divided into multiple layers to form the same multilayer planar structure, and the power amplifier circuit structure can be realized on each layer. At the same time, the standard waveguide facilitates standardized connection with the front and rear circuits. Under the working conditions of transmitting the main mod...

Abstract

The invention relates to a waveguide double antipodal fin-line and microstrip line type space power synthesizer which includes a connecting waveguide port, a transition structure, an anti-resonance piece and microstrip lines. The transition structure adopts metal gradual change fin lines of a cosine square equation to be printed on the obverse side and the reverse side of a dielectric substrate, the metal gradual change fin line on the obverse side is in transition into two microstrip lines, the metal gradual change fin line on the reverse side is used as ground, the anti-resonance piece is printed on the reverse side of the dielectric substrate, and the shape with semicircle at the two ends and rectangle in the center is adopted.

Description

Technical field [0001] The invention relates to the field of radar technology, in particular to a spatial power combiner in a radar solid-state transmitter. Background technique [0002] The high-power amplifier is one of the indispensable key components of the microwave or millimeter wave frequency band transmitter, which mainly realizes the power amplification function through electric vacuum devices or solid-state devices. For electric vacuum devices, because they are high-voltage devices, they need to provide a high-voltage power supply system in practical applications, so the volume and weight have certain restrictions on the application; for solid-state amplifier devices, they have the advantages of low voltage, small size, and light weight. Especially with the application of microstrip printed circuits in radar solid-state transmitters, solid-state amplifier devices can be used in a wider range of occasions. However, a single solid-state power amplifier device has lower po...
