As Revealed in Determine 12-16, a standard touring-wave amplifier employs a multi­phase low-go filter, consisting of both a transmission line or lumped inductances, with suitably pumped shunt varactor diodes furnishing the shunt capacitances. The signal and pump frequencies are applied on the enter conclusion from the circuit, as well as https://rf.vllis.com/en/product-category/narrowband-amplifier
