摘要： A triple-band bandpass filter with at least one cavity resonator. Each cavity resonator has the same three orthogonal resonances modes corresponding to three unique resonance frequencies. The three unique resonance frequencies define the passbands of the filter. The filter has an input probe coupled to an input cavity resonator. The filter has an output probe coupled to an output cavity resonator. The input and output probes are shaped to concurrently couple signal waveforms in each of the resonance modes. Coupling probes that can be used as input or output probes are also provided. An inter-cavity coupling operable to concurrently transmit signal waveforms in each of the resonance modes is also provided. The inter-cavity coupling can be used to transmit signals between adjacent cavity resonators in the filter.

摘要： A transmission line circuit assembly has a substrate layer having a transmission line trace, further having a functional portion and a transitional portion. An enclosure of the assembly houses the transitional portion of the transmission line trace. A first surface of a dielectric plug is conductively coupled to an inner top surface of the enclosure. A second surface of the plug is aligned and spaced apart from the transitional portion of the transmission line trace to define a gap therebetween. An interfacing portion of a connecting pin is housed within the enclosure and bonded to the transitional portion. A connecting portion of the pin is connectable to an external conductor. The gap may be filled with a dielectric material. The transitional portion, dielectric plug, dielectric filler and connecting pin form an electromagnetic transition providing tuning and matching of the function portion with the external conductor.

摘要： An inline microwave bandpass filter where cross coupling between non-adjacent resonators is realized by changing the orientation of selected resonators. The microwave bandpass filter includes a cavity and three or more resonators arranged in a row (or inline) in the cavity. At least one resonator has a different spatial orientation from at least one other resonator. For example, one or more of the resonators may be rotated 90 or 180 degrees with respect to one of the other resonators. This arrangement of resonators facilitates sequential coupling between pairs of adjacent resonators and cross coupling between at least one pair of non-adjacent resonators without the use of additional cross coupling structures such as dedicated coupling probes or extra cavities. One or more plates may be introduced between adjacent resonators to independently control the sequential and cross coupling.

摘要： A resonator cavity for supporting a plurality of resonant modes and filtering electromagnetic energy includes a cavity and a resonator element with a mounting flange. The cavity is defined by a top end wall, a bottom end wall and a sidewall and has a longitudinal axis along its length is defined. The resonator element is positioned within the cavity along the longitudinal axis and includes a mounting flange. The resonator element is only in physical contact with the cavity through the mounting flange at a mounting location and where at least one resonant mode of the electromagnetic energy exhibits a local minimum. The dimensions of the cavity and the resonator element are selected so that the associated electromagnetic energy is defined by an electromagnetic field pattern that substantially repeats itself at least twice along the length of the resonator.

摘要： Embodiments describe methods of correcting S-parameter measurements for a DUT. The method includes coupling at least one tracking module associated with a set of electrical standards to a S-parameter measurement device to form a test system. An initial calibration for the test system is then determined. This may include measuring the S-parameters of the electrical standards, generating a calibration along a calibration plane, generating a calibration along a correction plane and determining at least one error adapter from the calibrations. The DUT is coupled to the test system and the S-parameters of the DUT are measured. Changes in the initial calibration are tracked using the tracking modules. Tracking may include measuring the S-parameters of the electrical standards, generating a correction plane calibration and generating a corrected calibration plane calibration from the correction plane calibration and the error adapter(s). The measured S-parameters are corrected using the tracked changes.
