Abstract
The invention relates to an ultra-high frequency switching matrix. Only active components, i.e. field effect transistors, are used in the integrated circuit construction of the matrix according to the invention. Coupling between an input channel and an output channel is obtained by a power divider on the input channel, which is a bi-drain transistor or a differential amplifier, a controllable switch in the form of a bi-grid transistor or two transistors in series, and a power combiner on the output channel, which is a multi-grid transistor or several transistors in series. Application is to telecommunications, particularly satellite telecommunications.
