摘要： A microwave filter has a housing defining an inner cavity. A first resonator is positioned in a first portion of the inner cavity. A second resonator is positioned in a second portion of the inner cavity. A third resonator is positioned in a third portion of the inner cavity. The first resonator and the third resonator are cross-coupled via an iris. The second resonator is elongated and is coupled to the first resonator and the third resonator. The resulting microwave filter has a frequency response having a transmission zero in the lower stopband. A high-pass filter is realized without the use of a cross-coupling probe.

摘要： The present invention relates to a public cavity input multiplexer that is used to divide broadband signals into multi-channel narrowband signals according to the frequency and includes a public cavity and at least two channel filters. The public cavity is a broadband resonator that is used to input broadband signals, and is coupled with each of the channel filters respectively. In the input multiplexer of the present invention, no electric cable or waveguide and circulator are used for connection. The integrated design is achieved by establishing the public cavity and the channel filter, which reduces volume and mass, avoids the errors caused by influence on the circulator due to temperature change, enhances reliability, saves cost, and improves the electric performance. The design of the public cavity makes the input coupling accurate to calculate, convenient tuning and optimizes the consistency of channels.

摘要： A tunable bandpass filter to provide a constant absolute bandwidth across the entire tuning range. The filter comprises of a plurality of tunable resonators, each having an enclosure. A resonating structure extending upwardly from the bottom surface of the enclosure and a tuning screw with a flat head extending downwardly from the top surface of the enclosure, wherein the resonating structure and the flat head of the screw face each other and form a gap. The height of the tuning screw can be adjusted to change the gap between the resonating structure and the flat head. The adjustable gap of the present filter allows for tunable filter operation.

摘要： The invention relates to an adjustable resonator filter, which has a casing made up of a bottom, walls and a lid, which casing functions as a ground for a transmission path, which is divided with conductive partitions into resonator cavities, and on the transmission path of the resonator filter there is a coupling opening in the partitions separating subsequent cavities. In the casing there is by at least one partition a coupling space, which is open into both resonator cavities separated by the partition, which resonator filter has an inductive coupling member. This is arranged to extend through said coupling space into both resonator cavities. The inductive coupling member is in electric contact with the casing at least in one of the resonator cavities. In the coupling space there is a moveable conductive adjustment piece, which has a minimum position for the coupling and a maximum position for the coupling.
