    摘要： A microwave filter (1) comprises at least one resonant filter element (F, F1-F6) resonating at a resonant frequency (F0) and having a housing (11), a resonant filter cavity (C, C1-C6) arranged in the housing (11) and a resonator element (12) arranged in the housing. At least two tuning elements (13, 14) are arranged on the housing (11) of the resonant filter element (F, F1-F6) and each extend into the cavity (C, C1-C6) with a shaft portion (132, 142), wherein the two tuning elements (13, 14) are movable with respect to the housing (11) to adjust the length (L1, L2) of the shaft portion (132, 142) extending into the housing (11) and wherein the at least two tuning elements (13, 14) are constituted and designed such that by adjusting the length (L1, L2) of the shaft portion (132, 142) of each tuning element (13, 14) extending into the housing (11) a temperature drift of the resonant frequency (F0) is adjustable.

    摘要： A cavity filter has a resonator. The resonator is engaged by a rod having a mounting portion and a thermal dissipation portion. The mounting portion of the rod extends through the floor of the cavity filter to engage an internal surface of the resonator. The thermal dissipation portion dissipates heat from the resonator to the outside of the cavity filter.

    摘要： Apparatus for preventing energy leakage from a transmission line treats the line as a "partially closed" vessel. A gas stream with a pressure slightly different from ambient pressure is provided to the interior of the transmission line and a conduit that allows gas to pass between the transmission line and the ambient environment is provided. The gas flow rate at the conduit is then detected and monitored. If the flow rate falls outside a predetermined threshold, an electrical energy leakage is indicated. In another embodiment, the pressure of the input gas to the transmission line is continuously checked by a pressure switch, which will detect a change in pressure if the transmission integrity is compromised and disable the energy source.
