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 (Q1 Q2, Q′1 Q′2), one transistor (Q3, Q′3) controlled through the gate line (Lgc1) of the amplifier being associated with each cell, the associated transistor (Q3) of the first part controlling the state of the common-gate transistor (Q′1) of the second part and the associated transistor (Q′3) of the second part controlling the state of the common-gate transistor (Q1) of the first part, the two inputs (E1, E2) of the selector switch being the free ends of the gate lines (Ldc1) of the two distributed amplifiers (41, 42) and the outputs (S1, S2) of the selector switch being the free ends of these two amplifiers. The invention can be applied especially to digitally controlled phase control devices.
