Antenna switch for a communication terminal

摘要

The device has a first transmitter (Tx1) operating in a first frequency range and at least one second transmitter (Tx2) operating in a second range, an antenna (1) and a switching device (2) between transmitters and antenna. The transmitters can be connected to the antenna via switches (S1,S2) in the switching device. A blocking device (3) for the second frequency range is connected between the first transmitter and the switching device
