Abstract
A method and an equipment for controlling a multi-branch frequency-hopping receiver equipment used in a radio station, especially in a base station of a cellular radio system onto a desired frequency when a band-pass filter (BPF2) responsive to an external control signal (VBPF) has been arranged for each branch of the receiver equipment, the control signal (VBPF) of the band-pass filter being controlled in sync with frequency hopping. The control signals (VBPF) of the band-pass filter (BPF2) are determined for each frequency (C) and each filter (BPF2) and this information is stored in a tuning voltage memory (TVM) from which it is retrieved in sync with frequency hopping.
