摘要：
In this paper we present the design and development of a micromachined monolithic half coaxial transmission tine filter. The proposed transmission tine has an air gap between conductors, to provide low propagation losses, while allowing the use of wide center conductors to reduce conductor losses. Additionally by using a quartz substrate, dielectric losses are minimized. Out of experimental resonators we have extracted an unloaded quality factor of 141. The transmission line is used in the design of a three pole, capacitively coupled bandpass filter, having a 5% fractional bandwidth and a center frequency of 31.75 GHz.
