<p>The present invention relates to a distribution network which is an active power spiltter 1 to 2 (FC1A) or active power combiner 2 to 1 (FC+B) or alternatingly can be such a power splitter and such a poer combiner, said power splitter consisting to two distributed amplifiers with a common input and one output each, and said power combiner consisting of two distributed amplifiers with one input each and a common output. For said power splitter, a switching element (ST1,...,STN; ST'1,...,ST'N) is connected between each connection point on the outputs of the amplifying elements and earth, and for said power combiner, a switching element (ST1,...STN; ST'1, ...,ST'N) is connected between each connection point on the inputs of the amplifying elements and earth, said switching elements being optimised to take, depending on a control voltage, one of two distinct states. A first corresponding to a capacitance (Coff) and a second state correspohding to a low impedance short circuit (Ron). This implies that when thecontroal voltage is high for a distributed amplifier, i.e. half a power splitter or power combiner, this amplifier transmits power, and when the control voltage is low for a distributed amplifier, this amplifier does not transmit power. The invention also relates to a multifunctional broadband elctronically steered phased array system comprising at least one power splitter or power combiner as stated above.</p> |
