The Design of a W-band Waveguide Attenuator
Chuanxiang Chen, Xianbao Shi · 2023
With the research of terahertz technology becoming a hot spot, the waveguide attenuator used to control the signal level amplitude and simulate the attenuation of microwave and millimeter wave signals in the transmission process also plays an important role, and puts forward higher requirements for the frequency range, attenuation range and attenuation accuracy of the attenuator. A W-band waveguide attenuator is designed in this paper. The Voltage Standing Wave Ratio (VSWR) is less than 1.2, the insertion loss is less than 1.0dB, the attenuation accuracy at 60dB can reach 2.1dB, the attenuation range is 0dB~60dB, the resolution can reach 0.1 dB, and the resolution can reach 0.01dB in the attenuation range of 0dB~10dB.
