Abstract
An active selector switch with two inputs and two outputs comprises two parts, each part comprising a distributed amplifier whose elementary cells comprise at least two cascode-mounted transistors (Q Q , Q′ Q′ ), one transistor (Q , Q′ ) controlled through the gate line (Lgc ) of the amplifier being associated with each cell, the associated transistor (Q ) of the first part controlling the state of the common-gate transistor (Q′ ) of the second part and the associated transistor (Q′ ) of the second part controlling the state of the common-gate transistor (Q ) of the first part, the two inputs (E , E ) of the selector switch being the free ends of the gate lines (Ldc ) of the two distributed amplifiers ( ) and the outputs (S , S ) of the selector switch being the free ends of these two amplifiers. The invention can be applied especially to digitally controlled phase control devices.
