固态发射机中双工控制板的设计

固态发射机中发射前级一般采用双工模式。为实现发射前级的双路切换和可靠工作，需由一块双工控制板进行控制。文中介绍了双工控制板输入模块、内部逻辑模块和输出模块的设计。在实际应用中，该双工控制板很好地实现了发射前级的双工控制、驻波保护和过脉宽、过工作比保护。

Design of the Duplex Control Board in the Solid State Transmitter

In the solid state transmitter, the transmitter front stage adopts generally duplex control working mode. In order to realize duplex switching and reliable working of the transmitter front stage, a duplex control board must be designed to accomplish control of the front stage. The duplex control board performs the task of duplex control, over pulse width protection and over duty cycle protection of the transmitter front stage. This paper introduces in detail the input module design, the internal logic module design and the output module design. In real usage, this duplex control board has achieved well the duplex control, standing wave protection, over pulse-width protection and over duty cycle protection of the transmitter front stage.
