Claim Text:
1. A traveling wave amplifier, comprising: a plurality of amplifying units connected in parallel between an input port and an output port of the traveling wave amplifier, the amplifying units each having a cascade unit including: a switching transistor configured to receive an input modulating signal from the input port; a dynamic cascade transistor configured to output an amplified output signal to the output port, the dynamic cascade transistor feeding the amplified output thereof back to a base of the dynamic cascade transistor through a resistive divider; and a static cascade transistor configured to be driven by a first static bias provided to a base thereof, the static cascade transistor being put between the switching transistor and the dynamic cascade transistor, wherein the switching transistor, the static cascade transistor, and the dynamic cascade transistor are connected in series.
