  • Patent number: 10790795
    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.

  • Patent number: 10720686
    Abstract: A novel miniaturized horizontal split-wave orthomode transducer includes a common channel portion, a first polarized channel portion and a second polarized channel portion, and the centers of the openings of the first polarized channel and the second polarized channel are coaxially and respectively arranged on two opposite sides of the common channel portion to save the bend and extended structure at the rear end of the horizontal split-wave orthomode transducer and also save the occupied space since there is no need to guide signals in one of the polarization directions to the rear and return the signals, so as to further achieve the effects of improving the flexibility of installing the transducer, providing a good isolation between electromagnetic signals in different polarization directions and preventing the interference occurred between the electromagnetic signals.

  • Patent number: 10276905
    Abstract: A non-contact frequency automatic tuning filter with an antileakage chamber includes a first casing with a first cavity formed at a first opening of the first casing, a moving part, and a second cavity. The second cavity has a second casing, a chamber formed in the second casing, and second and third openings penetrating through the second casing. The moving part is plugged from the third opening into the first cavity or from the third opening into a space between the third opening and the first cavity. The second opening proximate to the moving part constitutes a part of the chamber. The second casing has a spacing portion proximate to the moving part for separating the moving part and chamber. The first and second casings are not in contact with the moving part. The invention can prevent leakage of electromagnetic waves and unstable frequency shifting.

  • Patent number: 9887444
    Abstract: A filter capable of adjusting frequency and bandwidth for dynamically setting at least one of the filter center frequency and bandwidth includes a first movable member, a second movable member, an upper casing, a lower casing, multiple conductive clamping members, a cavity and a driving module. The first and second movable members have multiple first and second lugs formed on the first and second boards respectively. The upper and lower casings have multiple upper and lower openings corresponsive to the first lugs and the second lugs respectively. The conductive clamping members are corresponsive to the upper openings and the lower openings. The cavity has multiple chambers and multiple connecting portions. The driving module changes the position of the first movable member to determine the filter center frequency and the position of the second movable member to determine the bandwidth.
