A circuit for the selective control of several antennas on the basis of a final stage common

摘要

Circuit allowing the selective control of several antennas on the basis of a final stage common. This circuit comprises a first switch (10), connected to a terminal (6) of the final stage (8) and connected to the choice to the two contacts of the switching (12, 22), a second switch (14) having a fixed contact, connected by an antenna (l1) to one of said contacts, a first contact of the switching (16), connected to the second terminal (18) of the final stage, and a second contact of the switching (20) connected to said first terminal of switching, a third switch (24) which can be switched in the same time as the second and comprising a fixed contact, connected by a second antenna (l2) to a second contact of the switching (22) of the first switch, a first contact of the switching (28), connected to said second terminal, and a second contact of the switching (26) connected to said second terminal of switching, and the other two antennas (l3, l4) connected to the fixed contacts of switches and to said second terminal.
