A switch comprises a first elastic element, an actuator-element mechanically coupled to a first side of the first elastic element, and a first switching conductor, mechanically coupled to a second side of the first elastic element. The switching conductor is configured for moving between a first conductor position and a second conductor position. The actuator-element is configured from moving between a first actuator-element position and a second actuator-element position separated by a predefined actuator-element lift, thereby moving the first side of the first elastic element. The first elastic element moreover is configured for converting a movement of the first side of the first elastic element by the predefined actuator-element lift into the movement of the second side of the first elastic element with a predefined elastic force.

Force-distance controlled mechanical switch

A high frequency switch is provided. The high frequency switch comprises a first high frequency connector, comprising a first inner conductor, integrally formed with a first strip conductor. Moreover, the high frequency switch comprises a second strip conductor arranged orthogonally in a first plane relative to the first strip conductor, a third strip conductor, arranged orthogonally in the first plane relative to the first strip conductor, a first switching conductor, having an orthogonally angled shape relative to the first plane, a second switching conductor, having an orthogonally angled shape relative to the first plane. A switching actuator is mechanically connected to the first switching conductor and to the second switching conductor adapted to move vertically relative to the first plane, to a first position and to a second position.

Switch for switching between different high frequency signals

An electronic microwave circuit () with field effect transistors which are integrated on at least one semiconductor chip (), has a light source (), which radiates the field effect transistors with light and possesses a housing () which encloses in a microwave excluding manner the semiconductor chip () and the light source () or a light conducting means () connected with the light source ().

Microwave switching with illuminated field effect transistors

Electronic switch () with two switching states (ON, OFF) possesses at least one field effect switching transistor (Q), input port (In) connected with source terminal (S), on which input signal (Vin) is present, output port (Out) connected with drain terminal, on which switched signal (Vout) is present, control port (Con) connected to gate terminal (G), on which is present signal (Vc) for controlling electronic switch () and switch apparatus (Sw), which creates the two switching states (ON, OFF) by means of a changing of control signal (Vc). Controlling signal (Vc), during at least one of the two switching states (ON, OFF) is, at least partially, formed by correction signal (Sc), which in turn is produced from input signal (Vin), so that the frequency dependent drop in voltage between the drain-source channel and the gate electrode of the field effect switching transistor (Q) is at least partially compensated.
