| Abstract: |
| In this paper, based on the principle of absorption attenuators, circular and Lance-shaped fixed attenuators are designed and simulated respectively. They can achieve 10dB and 20dB attenuation in the frequency range of 200-260 GHz, and their attenuation accuracy is less than ±1.3dB. |
| Key words: fixed attenuator terahertz return loss attenuation accuracy |
