摘要：
We present a broadband distributed power amplifier topology capable of providing efficiencies approaching 50%. Unlike tapered-drain-line power TWAs, high- Z(0) lines are not required, greatly improving realizability in MMIC implementation. An experimental hybrid achieved bandwidth 25% of f(tau) with similar to 15 dB gain and 30+/-5% power-added efficiency.
