    Abstract: The invention relates to a circuit configuration for providing a complex value local oscillator signal. Said configuration comprises two dual mixers (M1, M1', M2, M2') that are controlled on their input pairs by a signal processing circuit (1) by means of a reference signal supplied to an input (E, E') in such a manner that on the dual mixers adapted for frequency conversion, on the output side (A, A') thereof, an inphase and a quadrature component are provided and have an exact phase shift of 90 DEG relative each other and jointly form a complex value local oscillator signal. The circuit configuration is preferably used in a receiver for controlling a downlink frequency converter (12). The aforementioned principle allows reduction of the dependence of the frequency shift of 90 DEG on work tolerances, a reduced frequency dependence of the phase shift and a substantially reduced current consumption of a mobile radio receiver.

    Abstract: The invention relates to a demodulator and a demodulation method. The aim of the invention is to enable a reliable demodulation in the event of an overlap of the intermediate frequency range and the signal data frequency range. To this end, a rapidly oscillating output signal (14) is generated from the in-phase signal (11) and the quadrature signal (12), the sign of said output signal varying according to the product of the sign of the in-phase signal and of the quadrature signal. Either an XOR gate (13) or a multiplier stage can be used in order to produce one such output signal.

    Abstract: The invention relates to a transmitter system, especially for cellular telephony, which modulates a modulation signal (cos omega mt, sin omega mt) onto a low-frequency carrier signal (cos 1/3 omega t, sin 1/3 omega t) using two intermediate-frequency rejecting mixers (5, 6), and which translates the signal (cos 1/3 omega t+ omega mt, sin 1/3 omega t+ omega mt) thereby obtained and present on the outputs of the modulators (5, 6) as a complex signal due to the circuitry of the inventive transmitter system into a desired transmission frequency by means of a frequency translator (4). The invention combines the advantages of vector modulation at a relatively low frequency with the advantages of an intermediate-frequency rejection mixing during modulation.

    Abstract: Disclosed is a frequency converting circuit arrangement (14) supplying a complex-valued output signal at the output (2) thereof. Said circuit comprises two frequency mixers (3, 4) which are respectively triggered by an input signal and a feedback signal which represents the frequency-divided output signal and is divided into an in-phase component and a quadrature component. The inventive frequency converting circuit (14) makes it possible to supply in a frequency-precise manner that is independent of production tolerance a signal with one output frequency, said signal being supplied as an IQ signal and being decoupled frequency-wise from the input signal, wherefore said frequency converting circuit (14) is particularly suitable for mobile radio transceivers.

    Abstract: A traveling wave amplifier comprises a first normally off MOS transistor having a drain, source and gate terminal. The drain terminal is connected to a node of a drain line, which is connected to a first supply voltage potential via a connecting resistor. The gate terminal is connected to a node of a gate line, onto which an input signal is coupled. The source terminal is coupled to a second supply voltage potential via a first resistor. The traveling wave amplifier also comprises at least one second normally off MOS transistor. In addition, the traveling wave amplifier further comprises a normally off bias MOS transistor. The normally off bias MOS transistor forms a current mirror with at least one of the second normally off MOS transistors. An output signal of the traveling wave amplifier is tapped off on the drain line.
