Embodiment Construction

[0013] A spaceborne ferrite microwave front-end backup circuit, including: driver A1, driver B2, also includes: main excitation coil 3, auxiliary excitation coil 4, ferrite switch 5, wherein the ferrite switch 5 includes: ferrite Magnetic core 6 and cavity 7.

[0014] The cavity 7 of the ferrite switch 5 is a rectangular parallelepiped metal piece with a "Y" shaped cavity inside, and the ferrite core 6 is "Y" shaped, placed in the center of the "Y" shaped cavity, and connected to the cavity 7 glued in between. There are through holes on the three arms of the ferrite core 6, and there are two through holes on one side of the cavity 7. The main excitation coil 3 and the auxiliary excitation coil 4 pass through the three arms of the ferrite core 6 in parallel. Through holes on the arm, the two ends of the coil pass through the two through holes of the cavity 7 respectively. The output end of the driver A1 is connected to the main exciting coil 3 , and the output end of the driv...

Abstract

The invention discloses a satellite-borne ferrite microwave front-end backup circuit. The satellite-borne ferrite microwave front-end backup circuit comprises a driver A (1), a driver B (2), a main excitation coil (3), an auxiliary excitation coil (4) and a ferrite switch (5), wherein the ferrite switch (5) comprises a ferrite magnetic core (6) and a cavity (7); the ferrite magnetic core (6) is Y-shaped and arranged in the center of a Y-shaped cavity; and the main excitation coil (3) and the auxiliary excitation coil (4) penetrate through three supporting arms of the ferrite magnetic core (6) in parallel and then respectively extend out of two through holes of the cavity (7). The driver A (1) serves as a main driver circuit, the driver B (2) serves as a backup driver circuit, and under the control of a main control signal and a backup control signal, the driver A (1) and the driver B (2) cannot apply excitation signals to the ferrite switch (5) at the same time. The satellite-borne ferrite microwave front-end backup circuit has the advantages that system design is simplified, and requirements of satellite-borne products on high equipment reliability are met.

Description

technical field [0001] The invention relates to a microwave front-end backup circuit, in particular to a satellite-borne ferrite microwave front-end backup circuit. Background technique [0002] As a fast electronic switch, the space-borne ferrite microwave front-end is located between the transmitter, receiver and antenna of the space-borne microwave remote sensor to realize the switching of microwave measurement signals from the transmitter to the antenna and from the antenna to the receiver. Microwave remote sensors play an extremely important role, and higher requirements are put forward for their reliability. [0003] The traditional on-board ferrite microwave front-end adopts two identical sets of primary and secondary products to realize redundant design, so as to improve the reliability of the product. In the past, the microwave front-end circuit part included: driver A, excitation coil A, ferrite switch A, driver B, excitation coil B, and ferrite switch B. The dri...
