1. 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.
