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.

Circuit, switching module comprising the same, and use of said switching module

A method produces a component having a ceramic base body and contact surfaces on opposite sides of the ceramic base body. The method includes forming first protective layers on the opposite sides of the ceramic base body in regions not to be covered by the contact surfaces, forming second protective layers on opposite surfaces of the ceramic base body, sintering the ceramic base body with the first and second protective layers at a first temperature, forming the contact surfaces on the ceramic base body, and sintering the contact surfaces at a temperature that is lower than the first temperature.

Electroceramic component comprising a plurality of contact surfaces

An electrical component includes a ceramic base body having at least four contact surfaces. Two of the contact surfaces are on opposite sides of the ceramic base body. First protective layers are arranged on regions of the opposite sides of the ceramic base body that do not include the contact surfaces. The first protective layers have a composition that allows the first protective layers to be sintered at a higher temperature than the contact surfaces. Second protective layers are arranged on at least two opposite surfaces of the ceramic base body. The ceramic base body, the first protective layers, and the second protective layers are sintered together.

An electrical component includes a base body that contains dielectric layers. The dielectric layers are superimposed and contain ceramic. The component also includes outer contacts on an exterior of the base body, and a resistor in an interior of the base body located between two of the dielectric layers. The resistor is connected to the outer contacts, and is made from a layer that forms a path between the outer contacts. The path between the outer contacts has multiple bends.

Electrical multi-layer component

An electrical component includes stacked electrode layers arranged on a foundation. The stacked electrode layers include a first type of electrode layer and a second type of electrode layer. Dielectric layers separate the stacked electrode layers to form at least one capacitor. Two pairs of external contacts are arranged such that one external contact in each pair of external contacts is located on a side of the foundation and such that connections between each pair of external contacts overlap. A first pair of the external contacts connects to the first type of electrode layer and a second pair of the external contacts connects to the second type of electrode layer. The first type of electrode layer includes a first conductive layer which connects to at least one of the first pair of external contacts and the second type of electrode layer includes a second conductive layer which connects to at least one of the second pair of external contacts.
