Mobile phone terminal, having a transmitter stage, a receiver stage and an antenna switch-over and adapter stage which each have an arrangement of passive structural elements, which arrangement is assigned a multiplicity of electrostatic-mechanical microswitches or microrelays and which can be programmed by actuating a predetermined configuration of the microswitches or microrelays in, in each case, at least one functional parameter, in particular the frequency characteristic, and a programmable control unit.

Mobile phone terminal with programmable microelements

A programmable mobile phone terminal includes a transmitter stage, a receiver stage, a switch-over and adapter stage having an arrangement of passive structural elements connected to a plurality of microswitches or microrelays programmed by a predetermined configuration in at least one functional parameter, and a control unit associated with the transmitter stage and the receiver stage, for setting predetermined values of the functional parameter.

A tunable high-frequency capacitor includes first and second fixed electrodes, the first fixed electrode having a high-frequency input connection, and the second fixed electrode having a high-frequency output connection. A movable electrode is arranged facing and spaced apart from the fixed electrodes and is supported by means of a suspension which causes a displacement of the movable electrode in relation to the fixed electrode depending on a control signal that is applied.
