| Zusammenfassung: | 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. |
