摘要：

This paper presents new architectures for RF pulse width modulation (RF-PWM). They allow for very efficient and simple implementation of this class of modulators. Even for the 2.6-Ghz band, the modulator can now be built with standard components. The new concepts support binary and M-ary output alphabets. One variant is capable of generating M-ary RF-PWM signals by only deploying one switching device. The new architectures are derived analytically and are illustrated by simulation results. A recent hardware implementation of this concept proofs the efficiency of this approach.
