摘要： Until now, a switched 2-band concept of a mixer oscillator stage has been developed independently of a 3-band concept. The invention provides a mixer oscillator stage which can be used both with the switched 2-band concept and the 3-band concept without changing the architecture of the mixer oscillator stage. This is achieved by using a number of oscillators which exceeds the number of mixers and by coupling the mixer(s) and oscillators via switching means so as to switch between the different oscillators in dependence upon the part of the band converging the signal.

摘要： The invention relates to a radio receiver device having a tuning stage (2, 3) that can be varied with a tuning signal (VT) and is connected to a receiving antenna (1), a frequency converting stage (5) with a mixer oscillator (6) that may be controlled by the tuning signal (VT) for converting the high frequency signals received to a defined intermediate frequency (ZF) and post-processing stages to form an audible low frequency signal. Said equipment can be used in different countries without loosing the tuning characteristics of the tuning stage (2, 3) for different band ranges due to the fact that at least two tuning units (2, 3) are connected to the receiving antenna (1), which can be effectively switched separately and whose outputs are connected to the common frequency converting stage (5) by means of a switch (4) and due to the fact that the variable range of the mixer oscillator (6) is configured in such a way as to be switched when switching to one of the tuning units (2) is effected.

摘要： The invention relates to a band-pass filter which has a pass band with a comparatively large pass-band width while at the same time presenting comparatively steep sides leading towards the stop-band and little damping in the pass band. The band-pass filter comprises three parallel LC members (LP1, CP1; LP2, CP2; LP3, CP3) one of which is positioned between a band-pass filter inlet (IN) and a band-pass filter outlet (OUT) while the other two are connected with one of their connectors to a fixed reference potential (P).

摘要： In a differential oscillator means (535, 553, 521, 523, 549 and 551) are provided for making it possible to band switch the oscillator. This is obtained by means of cross connecting two transistors (501 and 503) and connecting inductors (509 and 511) to the transistors (501 and 503). The oscillator can be band switched by means of shortening a circuit comprising of two diodes (521 and 523). The switching time for the oscillator is very short since the oscillating circuit does not comprise any serially connected capacitors. In addition all frequency bands of the oscillator can be made impedance matched by means of adding an additional pair of varactor diodes (529 and 531).

摘要： A system is provided that can automatically adjust a tuned circuit to resonate at the frequency of an applied excitation signal. The error in the resonant frequency of the tuned circuit is determined in real time from signals derived from within the network. The system permits the use of a time varying excitation frequency in a high Q circuit, including modulation conveying information. The tuning information may be stored in a memory and used to set the tuning instantaneously in order to maintain resonance when the excitation frequency changes abruptly, for example when frequency shift keying is used.
