CIRCUIT FOR SELECTIVE CONTROL OF SEVERAL ANTENNAS FROM A COMMON FINAL STAGE

摘要

P Circuit allowing the selective control of several antennas from a common final stage. This circuit comprises a first switch (10), connected to a terminal (6) of the final stage (8) and optionally connected to two switching contacts (12, 22), a second switch (14) comprising a fixed contact , connected by an antenna (L1) to one of said contacts, a first switching contact (16), connected to the second terminal (18) of the final stage, and a second switching contact (20) connected to said first switching contact, a third switch (24) which can be switched at the same time as the second and comprising a fixed contact, connected by a second antenna (L2) to a second switching contact (22) of the first switch, a first contact switching (28), connected to said second switching terminal, and a second switching contact (26) connected to said second switching contact, and two other antennas (L3, L4) connected to the fixed contacts of the switches and to said second terminal. / P
