    • In order to compensate changes in the resonant frequency of the resonator occurring owing to fluctuations in the distance between the reference distance (ds) and an actual distance (ds±&Dgr;ds) in an RF strip line resonator with a strip line (10) which is arranged at a desired distance (ds) from a metallic conductor (11), the strip line (10) is curved. This curvature induces eddy currents in the conductor (11). The eddy currents bring about a reduction in the inductance of the RF strip line resonator. The smaller/larger the distance between the strip line and the metallic conductor becomes, the smaller/larger this inductance becomes. Since shortening/lengthening the distance between the two conductors is however also accompanied by an increase/reduction in the capacitance of the RF strip line resonator, with the correct dimensioning of the curved strip line the two aforesaid effects cancel one another out and the frequency of the RF strip line resonator is approximately stable with respect to the given fluctuations in distance.
    • 为了补偿由于在具有条带线(10)的RF带状线谐振器中由于参考距离(ds)和实际距离(ds±Deltads)之间的距离的波动而发生的共振器的谐振频率的变化, 以与金属导体(11)的期望距离(ds)布置,带状线(10)是弯曲的。 该曲率在导体(11)中引起涡流。 涡流导致RF带状线谐振器的电感降低。 带状线和金属导体之间的距离越小越小,该电感越小/越大。 由于缩短/延长两个导体之间的距离,伴随着RF带状线谐振器的电容的增加/减少,伴随着弯曲带状线的正确尺寸,两个上述效应相互抵消,频率 RF带状线谐振器相对于给定的距离波动近似稳定。

    • In order to minimize switching losses occurring in antenna switches for wireless antenna diversity telecommunications devices with two antennas, for example base station of a DECT cordless telephone, in each case an electronic switching element (SE1 . . . SE4), constructed for example as a PIN diode or switching diode, is arranged in a first signal path (SW1) from a transmitter (TR) to a first transmission/reception antenna (A1), a second signal path (SW2) from the transmitter (TR) to a second transmission/reception antenna (A2), a third signal path (SW3) from a receiver (RE) to the first transmission/reception antenna (A1) and a fourth signal path (SW4) from the receiver (RE) to the second transmission/reception antenna (A2). The switching elements (SE1 . . . SE4) form here, together with the signal paths (SW1 . . . SW4), a ring circuit.

    • For the demodulation of modulated carrier signals (AS) supplied to the cordless telecommunication apparatus, a data comparator (1212) is used in the cordless information transmission, especially a DECT-specific information transmission, which data comparator is supplied for this purpose with a reference signal (RS) generated by integration of the carrier signal (AS) at an input (E2) for the purpose of demodulating the carrier signal (AS). Since, according to the DECT transmission convention, two identical bit values of a synchronization word (S-BW) must also be detected in addition to the demodulation, a decision threshold (ES) of the reference signal (RS) is changed by an error value (dES). In the cordless telecommunication apparatus, a compensation arrangement (16, 19, 142) which compensates for this error value (dES) is therefore additionally provided.
