Abstract :
The possibility of realising 5th-or higher-order Cauer-Chebyshev lowpass filters by cascading rectangular microwave integrated structures is demonstrated. A new equivalent circuit of the rectangular element is introduced which accounts for the parasitic inductances due to higher-order modes. A simple adjusting procedure is developed which improves the passband behaviour of the filters, taking advantage of the presence of the parasitics.
