在行波管结构中可采用印刷电路来革除一般管中既昂贵又脆弱的螺状(慢波)结构。这样设计能缩小尺寸,降低成本,并且能在低电压工作。
Printed circuits can be used in traveling wave tube architectures to eliminate spiral (slow wave) structures that are both expensive and fragile in general pipework. This design can reduce the size, reduce costs, and can work at low voltage.
