Power switch comprising a switching circuit serially connected between input and output lines each having parallel branches therein

A power switch comprising:

• an input line of characteristic impedance Z0,
• an output line of characteristic impedance Z0, and
• a switching zone connected in series between the input line and the output line,
• the switching zone being constituted by N conducting branches bi in parallel, with N being an integer greater than or equal to 2 and i belonging to {1, . . . N},
• each conducting branch bi having, from the input line to the output line of the switch, an input line portion of characteristic impedance Zbei in series with a switching circuit ci in series with an output line portion of characteristic impedance Zbsi,
• wherein the switching circuit ci is configured, in a first state, to block the passage of a signal between the input line portion and the output line portion of the conducting branch bi and, in a second state, to transmit a signal between the input line portion and the output line portion of the conducting branch bi with a reflection coefficient less than or equal to 0.316, and
• wherein each of the input line portion of characteristic impedance Zbei and the output line portion of characteristic impedance Zbsi are between 0.75*N*Z0 and 1.35*N*Z0.
