Abstract
A zeroing structure applicable to an adjustable diplexer includes a substrate, holder, motor, lead screw, displacement plate, stop element and interference element. The holder is disposed on the substrate. The motor is disposed on the holder. The lead screw is rotatably disposed on the holder and connected to the motor, and thus rotation of the lead screw is driven by the motor. The displacement plate is movably disposed on the substrate and helically connected to the lead screw so as to undergo linear motion between a first position and a second position relative to the substrate when guided and driven by the motor. The stop element is disposed on the lead screw. The interference element is disposed on the displacement plate and at the position that allows the interference element to come into contact with the stop element when the displacement plate is at the first position. The zeroing structure enables the adjustable diplexer operable at an adjustable center frequency to perform mechanical zeroing and enables primary or auxiliary confirmation of zeroing detection. Furthermore, the zeroing structure is highly reliable and incurs low cost.
