As Proven in Determine 12-16, a standard touring-wave amplifier employs a multi­stage small-move filter, consisting of either a transmission line or lumped inductances, with suitably pumped shunt varactor diodes furnishing the shunt capacitances. The signal and pump frequencies are used with the input conclude from the circuit, and also the https://rf.vllis.com/en/product-category/narrowband-amplifier
