A diversity receiver comprising two receiver branches (RX1, RX2) with respective antennas (A1, A2), high- and intermediate-frequency parts, and means for generating signals (RSSIDET1, RSSIDET2) indicating the strength of signals received by the receiver branches; means (DA, TW, CO) for generating a control signal based on comparison between the signals (RSSIDET1, RSSIDET2) indicating the strength of the received signals; and switching means (CM) that switch a signal (AUDIO1, AUDIO2) from either one of the receiver branches (RX1, RX2) to a receiver output (DETECT), depending on the control signal. The means for generating the control signal comprise a differential amplifier connection (DA), a sawtooth generator (TW), and a comparator (CO). |
