Abstract

The invention discloses a phase modulation system of a microstrip line adjusting device. Four diodes are a first diode, a second diode, a third diode and a fourth diode. The cathode of the first diode is connected to the anode of the third diode. The cathode of the fourth diode is connected to the anode of the second diode. The cathode of the second diode is connected to the anode of the first diode through a short microstrip transmission line. The cathode of the third diode is connected to the anode of the fourth diode through a long microstrip transmission line. A connection line between the first diode and the third diode is connected to a first capacitor for signal access. A connection line between the fourth diode and the first diode is connected to the output end of a second capacitor. The system also comprises a first inverting amplifier. The first inverting amplifier is in series connection with a second inverting amplifier. The second inverting amplifier is in series connection with a resistor. The input end of the resistor is connected to the second inverting amplifier. A connection line between the fourth diode and the first diode is also connected to the output end of the resistor.

Description

technical field [0001] The invention relates to a phase modulation signal technology, in particular to a phase modulation system of a microstrip line adjustment device. Background technique [0002] There are three common ways to implement phase modulation, namely variable phase shift method phase modulation, variable delay method phase modulation, and vector synthesis method phase modulation. When the input microwave changes, the above common phase modulation methods need to change a large number of components, that is, set up a corresponding phase modulation circuit according to the input microwave parameters, so the above three phase modulation methods are very unsuitable for radar front-end technology. Therefore, we need to design a simple adaptable to different microwave input, and design a set of easy-to-change phase modulation circuit. Contents of the invention [0003] The object of the present invention is to provide a phase modulation system of a microstrip line...
