A DOOR SWITCHING CIRCUIT

Abstract

This invention relates to a compact gate switching circuit (GP) enabling high-speed and high-precision switching of power amplifiers (PAs) in a very small area. The gate switching circuit (GP) consists of: a first line (L1) containing a first switch (S1) and a second switch (S2); a second line (L2) containing a third switch (S3) and a first resistor (R1); at least one first power supply (PS1); at least one second power supply (PS2) adapted to generate control voltages for switching the first switch (S1), the second switch (S2) and the third switch (S3); at least one diode (D), a second resistor (Rpot) and a first capacitor (C1), each arranged on one of several lines extending between ground and the second line (L2); a third line (L3) extending from the first switch (S1) and the second switch (S2) to an output terminal (Tout); It includes a second capacitor (C2) that is electrically connected between the third line (L3) and ground.
