具有精细温度漂移调谐机构的微波滤波器
摘要：
具有温度漂移调谐机构的微波滤波器。微波滤波器(1)包括至少一个谐振滤波器元件(F，F1‑F6)，在谐振频率(F0)谐振，并且具有壳体(11)，置于壳体(11)内的谐振滤波器腔体(C，C1‑C6)，以及置于壳体内的谐振器元件(12)。至少两个调谐元件(13、14)置于谐振滤波器元件(F，F1‑F6)的壳体(11)上，并且每个调谐元件以轴部(132、142)延伸到腔体(C，C1‑C6)内，其中这两个调谐元件(13、14)能够相对于壳体(11)移动，以调整延伸到壳体(11)内的轴部(132、142)的长度(L1、L2)，并且这至少两个调谐元件(13、14)被构造与设计使得通过调整每个调谐元件(13、14)延伸到壳体(11)内的轴部(132、142)的长度(L1、L2)，能够调整谐振频率(F0)的温度漂移。
摘要（英）：

Microwave filter having a temperature drift tuning mechanism 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.
