Abstract :
Attenuators for W-band folded waveguide TWT have been successfully fabricated using BeO and Al2O3 respectively. And these samples could meet the strict dimension requirements based on former design after repetitious attempts. Test system of attenuator was developed to test them, and test results showed good performance that can meet the practical requirements in W-band folded waveguide TWT.
