A circuit array includes an antenna input, a signal input, a signal output, and a switch unit. The switch unit connects the antenna to either the signal input or the signal output. The antenna input is connected to a first productive device. The first protective device is a band-pass filter in a T configuration.

Bandpass filter electrostatic discharge protection device

The invention relates to a circuit comprising an antenna input (), a signal input () and a signal output (), and a switching unit (), wherein the antenna input () is connected to a first protection device () against electrostatic discharges, said first protection device () being a band-pass filter in a &#x3c0;-configuration. The advantage of the first protection device () is that it eliminates the need for a band-pass filter in the front end module, when used in a mobile telephone. Furthermore, the band-pass filter has a very good filtering characteristic, enabling ESD-related disturbances to be effectively suppressed. The invention also relates to a switching module and to the use of the same.
