摘要： The adjustable resonator according to the invention has a casing, which is composed of walls, a lid and a bottom, a resonator cavity inside the casing and an internal conductor inside the resonator cavity, which internal conductor is in electric contact with the casing. The resonator further comprises a moveable adjustment piece, which comprises a conductive adjustment member, a conductive upper plate, and a dielectric support member. The adjustment member has a stem, which is vertical, and a cap as an expansion thereof. The adjustment member can be moved downwards so that its stem and the fixed internal conductor connected to the bottom of the resonator go within each other. The movement of the adjustment piece in the coaxial resonator first decreases the resonance frequency and then slowly increases it. Therefore the resonator provides a very wide adjustment area for the resonance frequency.

摘要： An adjustable resonator filter comprised of cavity resonators. There is a movable conductive tuning element in the filter for adjusting each electromagnetic coupling, which element is located outside the resonator cavities. When the coupling between two resonators is the case, the movement of the tuning element changes the coupling between the signal ground and a fixed coupling element which extends from a resonator cavity to the next cavity, whereupon the strength of the coupling between the resonators changes. When the coupling between a resonator and the input/output line of the filter is the case, by means of the tuning element it is implemented a section with a low impedance inside a range with a relatively high impedance on the transmission path. This section moves together with the tuning element, in which case the strength of the coupling between the resonator and the line changes.

摘要： An adaptable filter made up of cavity resonators. The adaptation takes place by adjusting the connection from the input connector (CN1) of the filter to the input resonator and from the output resonator to the output connector. For adjusting the connection there is a coaxial transfer line (TL1), the outer conductor (OC1) of which is connected by its one end to the wall of the filter casing and by its other end to the outer conductor of the connector (CN1) and the inner conductor of which extends from the middle conductor of the connector to the cavity of the resonator and there into the internal connecting member of the resonator. A middle rod belonging to the inner conductor is surrounded over a certain distance by a cylindrical conductive tuning element, which can be moved by sliding it along the middle rod.

摘要： An arrangement for processing the antenna signal of a radio receiver and for leading it to low-noise amplifiers LNA of parallel amplifier branches. On the transmission path of the receiver from the antenna to the amplifiers LNA, functionally different elements are combined into physically united elements, such as the conductors (432, 433) of the low-passing part of the antenna filter and the division conductors of the Wilkinson divider (430), and the conductor (441) of the phase-shifter and the inductive part (L1) of the LNA matching circuit. Each physically united element is a conductor, which is insulated from the ground plane by air or a low-loss dielectric material. The arrangement reduces the number of lossy parts between the antenna and the amplifiers, and placing these parts on an ordinary circuit board is also avoided. For these reasons, inferior noise values compared to the prior art can be allowed for each LNA. In addition, the matching of the input impedance of the LNA becomes more accurate when no discrete coil is needed in it. FIG. 4

摘要： An arrangement for dividing the output signal of the antenna filter of a radio receiver to two different paths, such as two parallel low-noise amplifier branches of a base station. The divider circuit is physically integrated into a resonator-type antenna filter (RXF). This takes place by placing some conductors (332, 333) of the divider inside some conductive part of the filter structure or the resonator cavity and by using the coupling conductor (331) of the output resonator as part of the input line of the divider at the same time. As the divider is used a Wilkinson divider. Due to the arrangement, a transmission line between the antenna filter and the divider becomes unnecessary, and the dielectric losses of the divider are reduced as compared to the prior art, in which case correspondingly inferior noise qualities can be allowed for low-noise amplifiers.

摘要： A band stop filter (300) implemented by coaxial resonators for filtering antenna signals particularly in base stations of mobile communication networks. The starting point is a structure with a transmitting line and coaxial resonators electromagnetically coupled parallel with it, the natural frequencies of which resonators differ from each other slightly. The resonators (R1, R2, R3) form a unitary conductive resonator housing (310), the inner space of which has been divided into resonator cavities by conductive partition walls. In the invention, the center conductor (321) of the transmitting line is placed inside the resonator housing so that it runs across all the resonator cavities, and the housing functions as the outer conductor of the transmitting line at the same time. The resonator cavities are thus a part of the cavity of the transmitting line. When an electromagnetic field of the same frequency as the natural frequency of a resonator occurs in the transmitting line, the resonator in question starts to oscillate, causing the field to reflect back towards the feeding source. The strength of the resonance and the width of its range of influence at the same time are set, for example, by choosing the distance between the inner conductor (301) of the resonator and the center conductor (321) of the transmitting line suitably. The number of structural parts and metallic junctions in the band stop filter are relatively small. Therefore less intermodulation occurs in the filter than in corresponding known filters. Other functional units can also be easily integrated into the filter structure.
