RECEIVER DEVICE, ESPECIALLY FOR MOBILE RADIO

摘要

The invention relates to a receiver device, especially for mobile radio, which enables the use of slow transient phase control circuits during a two-point connection of a two transmitter-receiver, also in a heterodyne receiver structure. The need to carry out a channel change between the transmission and reception slot is avoided by providing a switching device for exchanging inphase and quadrature components(8, 9) on the input side of a step-down controller (1). As a result, either the upper side band or the lower side band of a useful signal are down-mixed without the need for exchanging channels.
