Abstract

The invention relates to a solid state amplifier parallel overload protection control system and a control method of the same, for solving the problem that in the prior art, the solid state amplifierparallel overload protection control system cannot realize parallel interactive overload protection of two types of data. The solid state amplifier parallel overload protection control system generates direct and indirect effect on a control signal of a coaxial RF switch through a low voltage controller, and an indirect control signal acts on a switch controller when direct signal control fails orthe output power is overloaded, and then a generated voltage pulse signal acts on the coaxial RF switch. The solid state amplifier parallel overload protection control system has the advantages of being simple in structure, being able to perform hardware programming, and realizing accurate and quick control. The solid state amplifier parallel overload protection control system can be widely applied to the microwave field.

Description

technical field [0001] The invention relates to the microwave field, in particular to a solid-state amplifier parallel overload protection control system and a control method thereof. Background technique [0002] At present, solid-state amplifiers are widely used in various microwave devices such as accelerators, phased radars, and satellite communications, and play an irreplaceable role in national security and strategy. In practical applications, when the input power Pin or reflected power Prf is overloaded, the solid-state amplifier needs to disconnect the input power Pin to realize self-protection. Self-protection of the solid-state amplifier is achieved even in the event of failure of the overload protection circuit. In addition, the maximum output power Pout that different loads can withstand is different. When the maximum output power Pout that different loads can withstand does not exceed the saturated output power Pout of the solid-state amplifier, for a specific ...
