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.

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： Dielectrics fixed on holders respectively provided at semi-coaxial cavity resonator stages are movably inserted through an outer conductor. The holders projecting out of the outer conductor are coupled to a coupling member, and the coupling member is directed to slide or turn, so that distances between the dielectrics and the inner conductors of the resonators are varied, and accordingly frequencies of the resonators are varied at the same time. Accordingly, there is provided a tunable filter that avoids an increase in insertion loss, is high-power resistant, does not cause intermodulation, and allows a center frequency of the filter to be varied steplessly and quickly.

摘要： An adjustable resonator filter (200), the operating band of which can be shifted by a one-time adjustment. The natural frequency of each resonator (210, 220) is affected, in addition to the basic tuning arrangement, by an adjustment circuit (ACI), which includes a fixed tuning element (280) in the resonator cavity and an adjusting part (290) outside the cavity. The tuning element has an electromagnetic coupling to the basic structure of the resonator. The adjustment circuit is functionally a short transmission line, which is “seen” by the resonator as a reactance of a certain value. By changing the electric length of the transmission line, the value of the reactance and the electric length and natural frequency of the whole resonator are changed. The change is implemented in the adjustment part by means of switches or a movable dielectric piece. In the resonator filter each resonator has a similar adjustment circuit, and the adjustment circuits have common control (CNT) for shifting the band of the filter. When the subband division is in use, the filters need not be separately adjusted for each subband in connection with the manufacture. No moving parts are required inside the filter housing.

摘要： The invention relates to a tunable resonator filter. In each resonator cavity of the filter there is a movable dielectric tuning element (728; 748) to adjust the resonator's natural frequency. The tuning elements are advantageously arranged to be moved by a common control implemented by a rod (708) joining them together, to shift the filter's band through equal displacements of the natural frequencies of the resonators. When the tuning element is moved horizontally sidewards from the resonator (710; 720; 730; 740; 750; 760) axis, the electrical length and natural frequency of the resonator change. In that case, when sub-bands are used it is not necessary to tune the filters separately for each sub-band in the stage of manufacture, as the sub-band can be chosen when the filter is put into use. The tuning elements can be movable also in each resonator separately, to implement the basic tuning in connection with the manufacture of the filter. The basic tuning can be automated, in other words it can be made without inconvenient handwork.
