Abstract

A hermetically sealed HF front end (e.g. a transmission/reception module) in a multilayer structure that includes electronic components is provided. The multilayer structure contains a plurality of substrates stacked one above the other and carrying the components. Grooves are formed in the substrates and sealing elements are provided between the substrates, which sealing elements engage in the grooves, and the substrates are soldered together.
