摘要：
A Ku-band transversal filter with a center frequency of 12 GHz and a bandwidth of 6 GHz using directional couplers made of a multilayer ceramic has been proposed and developed. The directional coupler can realize a wide range of frequency characteristics, e.g. coupling of 3.5 +/- 0.5 dB in the frequency range of 10 to 17 GHz and a wide range of coupling values, i.e. 3 to 35 dB. Calculations have confirmed that the increase in insertion loss due to a decreasing Q-factor can be much less than that for a resonator filter. The transversal filter was fabricated without additional tuning, and measured results agreed well with calculated values.
