Patent

CA 2256330

A mobile telephone repeater with a variable bandwidth is disclosed. The repeater comprises an uplink and downlink, each being provided with amplifier chains (6). Each chain comprises at least two band pass filter units (10, 11) coupled in series and having controllable pass bands, which at least partially overlap each other. The centre frequency of the filter units are controllable so as to make the bandwidth of the resulting pass band variable. Consequently, the effective bandwidth of the amplifier chain is controllable.

On décrit un répétiteur à largeur de bande variable, destiné à des téléphones mobiles et comprenant une liaison amont et une liaison aval, chaque liaison étant pourvue de chaînes d'amplificateurs (6) qui comportent chacune au moins deux filtres passe-bande (10, 11) couplés en série et présentant des bandes passantes, lesquelles peuvent être commandées et se chevauchent les unes les autres, au moins partiellement. On peut également commander la fréquence centrale des filtres de façon à faire varier la largeur des bandes passantes résultantes. En conséquence, on peut commander la largeur de bande efficace de la chaîne d'amplificateurs.
