As Shown in Determine 12-sixteen, an average traveling-wave amplifier employs a multi­stage minimal-pass 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 enter close in the circuit, plus the demanded https://rf.vllis.com/en/product-category/narrowband-amplifier
