For wireless power transfer and energy harvesting applications, an
advantage of having a broadband rectifier is the coverage of a wide
range of narrowband frequencies as well as wideband pulses. Many
broadband rectifiers have been recently proposed, but their reported
characteristics are mainly evaluated at discrete frequencies. Due to the
nonlinear nature of rectifiers, such frequency domain characteristics
may not directly correspond to the time-domain, especially when input
signals are wideband pulses. Here report the performance evaluation of a
broadband rectifier on wideband pulses with various pulse parameters. We
use our recently proposed broadband rectifier as a test device. Using
Gaussian-modulated RF pulses with various pulse parameters, the
rectification performance is verified via simulation and measurement.
The results demonstrate sufficient rectification efficiency even for
short pulses under appropriate parameters, where a maximum rectification
efficiency of 71 % is obtained.
