Abstract

The invention is applicable to the technical field of microwave equipment, and provides a detection-based active microwave amplitude limiter and a communication system, the amplitude limiter comprises a bidirectional coupler, a first detection module, a second detection module, an amplitude limiting driving module, a PIN diode, an antenna end and a power transmitting end; the output end of the first detection module is connected with the first input end of the amplitude limiting driving module, and the output end of the second detection module is connected with the second input end of the amplitude limiting driving module; the amplitude limiting driving module generates a driving signal according to a first detection signal output by the first detection module and a second detection signal output by the second detection module, and drives the PIN diode to be conducted. Based on the characteristics of the bidirectional coupler, when a high-power signal is injected into an antenna end, the forward detection output and the reverse detection output act on the positive electrode of the PIN diode in a superposed manner to drive the PIN diode to be conducted, so that one-way protection of the high-power signal is realized.

Description

technical field [0001] The invention belongs to the technical field of microwave equipment, in particular to a detection-based active microwave limiter and a communication system. Background technique [0002] The microwave limiter is a power modulation device. When the power is low, the signal passes through almost without attenuation, but when the input power increases to a certain value, the signal will be greatly attenuated. It is often used for the protection of receivers. protection of the low noise amplifier. [0003] In the prior art, the microwave limiter is usually bidirectional, which cannot be used for unidirectional protection of the transmitter, lacks a unidirectional limiter, and cannot meet practical application requirements. Contents of the invention [0004] In view of this, an embodiment of the present invention provides a detection-based active microwave limiter and a communication system to solve the problem that microwave limiters in the prior art ar...
