E 2 is Pin2 = x [6, 7]; the total efficiency on the two:1 dual RF-DC rectifier circuit is usually calculated on the basis from the formula beneath: PCE =x 3(4- x)/ 32×3(7-2x)/ three 3x Pin = 3x 9.9mWx 3( x -2)/ 32×3(2x -5)/4. five. six.100 50It could be observed from the mathematical derivation described above that the dynamic energy variety with the two:1 dual RF-DC rectifier for efficiency above 50 is Pin = 3x [8.1, 9.9]mW, reaching 1.eight mW. In comparison with the single microwave rectification achieved by each and every circuit, this represents an increase of 0.8mw, which might be attributed towards the two:1 dual RF-DC microwave rectifier circuit overcoming the limitations with the person diode rectification circuits with respect to high-power input response capacity. Higher power is inputted in to the HSMS2820 Schottky diode, which has stronger high-power input response ability, though low energy is inputted in to the HSMS2860 Schottky diode, which possesses a good response to low energy, hence completely taking advantage with the unique diodes’ rectification capacity for the applicable dynamic input ranges in an effort to further optimize all round circuit efficiency and preserve the stability of total circuit rectification efficiency over a bigger dynamic range of input energy. This really is very significant for MWPT technique engineering applications. five. Conclusions and Prospects A dual RF-DC microwave rectifier circuit primarily based on an unequal Wilkinson power divider was made in this paper. This rectifier circuit was made with two input power components in the ratio of two:1, passing by means of HSMS2820 and HSMS2860 Schottky diodes with distinctive power response characteristics. Assuming optimized impedance matching for each and every rectifier circuit, we compared the all round dynamic energy range in the circuit together with the dynamic power variety of every individual circuit. When compared with the HSMS2820 circuit, the dynamic power ranges above efficiency values of 60 and 50 were increased by 4 dBm and three dBm, respectively. In comparison with the HSMS2860 circuit, the dynamic energy ranges above efficiency values of 60 and 50 had been improved by five dBm and two dBm, respectively, indicating that, relative to traditional rectifier circuits, the 2:1 RF-DC microwave rectifier circuit is improved in a position to enhance the dynamic energy range though enabling the MWPT technique to preserve somewhat steady RF-DC transfer efficiency in continuously changing environments. Ultimately, a typical mathematical model was constructed to demonstrate the rationality of this conclusion.Author Contributions: Conceptualization, C.P.; Information curation, C.P. and C.C.; Formal evaluation, C.P. and J.W.; Isophorone Protocol funding acquisition, Z.Y. and C.C.; Investigation, C.P. and Z.Y.; Methodology, C.P.; ProjectElectronics 2021, 10,11 ofadministration, C.P. and C.C.; Sources, Z.Y. and Z.W.; Chlorobutanol custom synthesis Computer software, J.W. and Z.W.; Writing–review editing, J.W.
