专利汇可以提供Stripline video pulse generator专利检索,专利查询,专利分析的服务。并且Nanosecond video pulses are generated by a pulse forming network comprising input and output stripline sections connected by a drive inductance, a capacitor connected to ground and to the inductance by a variable tap, a potentiometer connected between the input stripline section and ground, and a step recovery diode connected between the output stripline section and ground. Input pulses fed through the drive inductance provide almost constant current drive to the step recovery diode. When the step recovery diode snaps, the step wavefront travels in both directions along the stripline. The reverse traveling wave is reflected at the AC short circuit produced by the capacitor. Pulse width is controlled by the location of the tap on the drive inductance. Pulse delay is controlled by the forward bias current through the step recovery diode by means of the potentiometer.,下面是Stripline video pulse generator专利的具体信息内容。

1. A video pulse generator comprising an input transmission line section, an output transmission line section, an inductor, said inductor being connected between said input and output transmission line sections, a step recovery diode connected between said output transmission line section and ground, a variable tap operably engaged with said inductor, a capacitor connected between said variable tap and ground, a potentiometer connected bEtween said input transmission line section and ground, input means connected between said input transmission line section and ground, and output means connected between said output transmission line section and ground.
2. A video pulse generator as defined in claim 1 including an emitter follower connected between said input means and said input transmission line section.
3. A video pulse generator as defined in claim 2 wherein said input transmission line section comprises a 50 ohm stripline segment, and said output transmission line section comprises first and second 50 ohm stripline segments and a capacitor, said capacitor connecting said first and second 50 ohm stripline segments.
