    • The invention relates to a method and an arrangement for tuning a combiner filter. The tuning comprises two separate tuning modes: coarse adjustment applied when the combiner is taken into use byutilizing a measuring branch (233B, 232B) for forward power (IFF) and a coarse measuring branch (235, 236, 237) for reflected power (IFR); and fine adjustment applied in continuous operation by utilizing the measuring branch for forward power (IFF) and a fine measuring branch (233A, 232A) for reflected power (IFR). The two-stage adjustment decreases the mutual interference of the filters during tuning. The correct tuning frequency of the combiner filter is obtained as the average point of the reversing points obtained in the adjustment process, the filter (10) being driven to the average position. This so-called positional average tuning has two advantages: the effect of noise present in the power measuring line is reduced, and the tuning error caused by the termination of the dynamics of the A/D converter positioned after the detector at low power levels and good combiner filter settings is diminished. Power measurements are made frequency-selective by mixing (210, 220).
    • 本发明涉及一种用于调谐组合器滤波器的方法和装置。 调谐包括两个单独的调谐模式:通过利用用于正向功率(IFF)的测量分支(233B,232B)和用于反射功率的粗测量分支(235,236,237)来使用组合器时所应用的粗调 ); 并通过利用正向功率的测量分支(IFF)和用于反射功率的精细测量分支(233A,232A)进行连续运行的微调。 两级调整可减少调谐过程中滤波器的相互干扰。 获得组合器滤波器的正确调谐频率作为在调整过程中获得的反转点的平均点,滤波器(10)被驱动到平均位置。 这种所谓的位置平均调谐具有两个优点:功率测量线路中存在的噪声的影响减小,并且调谐误差由位于检测器处于低功率水平的A / D转换器的动态结束引起;以及 良好的组合器滤波器设置减少。 功率测量通过混合(210,220)进行频率选择。

    • The invention relates to a device for tuning a combiner filter. In the invention the measuring signals (Pr1...Prn, PF1...PFn) of a number of different combiner filters are multiplexed to the same detectors (23). Multiplexing allows the measuring and adjusting electronics required by the tuning and adjusting means of combiner filters to be simplified considerably especially with a high number of combiner filters. Multiplexing of measuring signals is used primarily to select the sample signals of the forward and reflected power of one and the same combiner filter to be tuned for the measuring electronics. In the invention selectors (21, 22) for reflected power and forward power are independent of each other, which allows isolation measurement between different channels. The sample signal of the forward power of one combiner filter and the sample signal of the reflected power of another combiner filter are thus connected to the measuring electronics. When both sample signals undergo frequency-selective detection at the same frequency, the degree of isolation between the radio channels will be determined. The invention also relates to a method for performing isolation measurement on radio transmitters isolated by combiner filters.

    • The invention relates to a device and a method for adjusting a band-pass filter, especially a combiner filter. The method comprises deriving an RF sample signal proportional to the power of a modulated RF signal passing forward to the band-pass filter, reflected (Pr) from the input of the band-pass filter or passed through (Pf) the band-pass filter; down-converting (24, 29, 31) the sample signal by another RF signal (LO); detecting (28, 34) the signal strength of the mixing result; adjusting the centre frequency of the passband of the band-pass filter (22) on the basis of the detected signal strength. In the invention there is an essential frequency or modulation difference between the signals to be mixed, and so the mixing result will be an AC signal of a lower frequency. No accurate adjustment of the phase relation of the signals to be mixed is required. In the preferred embodiment of the invention, the frequency or phase difference between the signals to be mixed is accomplished by utilizing the phase modulation contained in the transmission when one of the signals is unmodulated. The DC component is filtered off the AC signal, which eliminates the measuring problems caused by the DC offset properties of the mixer (29, 31).
    • 本发明涉及一种用于调整带通滤波器,特别是组合滤波器的装置和方法。 该方法包括导出与通过带通滤波器的调制RF信号的功率成比例的RF采样信号,从带通滤波器的输入反射(Pr)或通过(Pf)带通滤波器 ; 通过另一个RF信号(LO)对采样信号进行下变换(24,29,31); 检测(28,34)混合结果的信号强度; 基于检测到的信号强度来调整带通滤波器(22)的通带的中心频率。 在本发明中,要混合的信号之间存在基本的频率或调制差异,因此混合结果将是较低频率的AC信号。 不需要准确调整要混合的信号的相位关系。 在本发明的优选实施例中,要混合的信号之间的频率或相位差通过利用传输中包含的相位调制来实现,其中一个信号未被调制。 DC分量从AC信号中滤除,消除了由混频器(29,31)的DC偏移特性引起的测量问题。
