摘要： Beam control pulse modulation (CPM) in an RF transmitter tube (101) is provided by a solid state switch on (S1) connected between the cathode power supply (103) and the cathode (102) of the transmitter tube. The beam controlling element (104) is returned to the normal cathode power source such that closing the switch (S1) between the two cathodes and the cathode power source brings the beam controlling element voltage to cathode potential causing beam current to flow, while opening the switch (S1) provides a very high equivalent cathode resistance, which self-biases the tube in the cutoff region, eliminating the need for a separate 'off' voltage power supply. Off-edge performance may be further improved by providing an off switch (S2) connected between the cathode (102) and a collector tap on the cathode power supply (103), and closing the switch (S2) when the on switch (S1) is opened to accelerate return of the cathode potential to the cutoff voltage.
摘要翻译： 射频发射器管（101）中的射束控制脉冲调制（CPM）由连接在发射器管的阴极电源（103）和阴极（102）之间的（S1）上的固态开关提供。 束控制元件（104）返回到正常阴极电源，使得闭合两个阴极之间的开关（S1），并且阴极电源使束控制元件电压成为引起束电流流动的阴极电势，同时打开 开关（S1）提供非常高的等效阴极电阻，该电阻在截止区域中对管进行自偏置，从而不需要单独的“断开”电压电源。 通过提供连接在阴极（102）和阴极电源（103）上的集电极接头之间的断开开关（S2），并且当接通开关（S1）断开时闭合开关（S2） 被打开以加速阴极电位返回到截止电压。
