Problems solved by technology

[0003] Since the main operating frequency bands of current radar transmitters cover C-band, X-band and Ku-band, however, the operating frequency band of most radar transmitters is limited to a single band, and it is difficult to cover multiple continuous bands

Abstract

The invention relates to an ultra-wideband two-path high-power distributor, and belongs to the technical field of radars. The square coaxial cable filled with the air medium is selected as a transmission line, so that the purpose of low-loss transmission of a high-power signal in a full frequency band of 6-18GHz is achieved; the discontinuity of the T-shaped structure is compensated by introducing the boss at the outer conductor; by introducing the impedance conversion section at the inner conductor, good impedance matching is realized. Through the design of the links, the two-path high-power distributor with the working frequency range covering 6-18GHz based on the square coaxial is realized.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a two-way power divider based on square coaxial, which can be applied to radar transmitters whose operating frequency range is 6-18 GHz. Background technique [0002] In a radar system, in order to increase the detection and operating range, it is necessary to increase the output power of the transmitter. As the frequency increases, the output power of a single solid-state device will decrease rapidly. In the microwave frequency band, the output power of these devices is generally only a few watts; at the same time, the frequency increases and the wavelength becomes shorter, resulting in more space for heat dissipation and matching. Smaller, the difficulty of processing also increases. Therefore, in the practical application of radar transmitters, power dividers are often used to achieve high power output. [0003] Since the main operating frequency bands of current radar transmi...
