Abstract: A signal conditioning circuit contains an oscillator which is connected to the inputs of two mixers. The output of one mixer is coupled, so as to form a feedback path, to a frequency divider circuit whose first output is coupled to the second input of the first mixer. A second signal output of the frequency divider circuit carries a signal with a phase shift of 90 degrees with respect to the signal at the first signal output of the frequency divider circuit. The second signal is supplied to a second input of the second mixer. Feedback results in undesirable signal components in the in-phase and quadrature components being suppressed. At the same time, the in-phase and quadrature components have a fixed phase relationship with respect to one another. The signal conditioning circuit allows desired non-integer division ratios to be achieved.

Abstract: The invention specifies a circuit arrangement with a phase locked loop (1), which can be used as a mobile radio transmitter, in particular. The reference frequency for the PLL (1), which is provided by means of the source (3), is multiplied by a multiplier (10) and is down-converted to an intermediate-frequency level in a down-conversion mixer (9) using the output signal from the PLL, and is evaluated such that a modulator (13) connected to the input of the oscillator (6) can be trimmed. The inventive principle is used to advantage in two-point modulators and allows inexpensive, integratable mobile radio transmitters with good noise characteristics.

Abstract: A radio receiver with a low intermediate frequency has a first mixer stage that can be fed with a modulated input signal and at whose output a complex intermediate frequency signal can be derived. Connected downstream of the first mixer stage is a limiting amplifier at whose output the intermediate frequency signal is present in a discrete-value and continuous-time fashion. A sampling device, for sampling the intermediate frequency signal, and a digital demodulator unit are connected to the output of this limiter. The demodulated input signal can be derived at the output of this digital demodulator unit. The present radio receiver requires a low chip area in conjunction with low power consumption, but offers a high sensitivity and accuracy based on the digitally implemented demodulation.

Abstract: The invention relates to a demodulator and also a demodulation method and enables a reliable demodulation even when the intermediate frequency range overlaps the range of the data frequencies of the signal. For this purpose, a rapidly oscillating output signal is generated from the in-phase signal and also the quadrature signal, the sign of which output signal varies in a manner dependent on the product of the signs of the in-phase signal and of the quadrature signal. Either an XOR gate or a multiplier stage may be used in order to generate an output signal of this type.
