Linearization network for satellite traveling wave tube
Abstract
A 4 GHz/13 W traveling wave tube linearizer was developed, aiming at a twofold increase in the linear drive range with respect to AM-AM conversion and phase linearity. This design was realized using an automatic constant gain/phase control circuit. The AM-FM linearization network is an electronic, controlled attenuator with PIN diodes while the tube phase linearization network makes use of a variable varactor diode phase shifter. The AM-AM linearizer realized improves the linear drive range by 3 dB while the phase linearizer reduces the phase shift by 50%.
