Abstract (en)
[origin: FR2890258A1] The device has a laterally mused metal oxide semiconductor (LDMOS) transistor whose gate (G) receives a frequency modulated signal and supplied by a gate voltage. A drain (D) of the transistor is connected to a DC supply by a low power switch (10) of an amplifier. The switch is controlled by a modulated signal transmission synchronizing signal. A rapid bidirectional surge suppressor (12) suppresses voltage value comprised between a peak supply of the drain and a drain source breakdown voltage. A control device controls opening and closing of the switch. An independent claim is also included for a method of amplifying pulsed radio frequency signals.
