- Abstract
- This letter presents a broad dual-band rectifier with a wide input power range that employs a dual-band matched voltage doubler (DMVD). The DMVD is composed of a voltage doubler and L-type matching networks connected with each diode; it transforms the input reactance of each diode independently over wide input power and broad dual-band ranges, thereby widening the dynamic input power range. The proposed rectifier was implemented with the dimensions of 40 mm x 15 mm. Measurements reveal that the power conversion efficiency (PCE) was maintained at over 50% in the wide input power ranges of 10.3-32 dBm and 13.5-31.5 dBm at 0.915 and 2.45 GHz, respectively. PCEs exceeding 50% were measured over frequency ranges of 0.3-1.1 GHz and 1.5-2.6 GHz.
