No need for an inductor, use an oscilator and voltage doubler. Seen on the net somewhere a diagram for making a voltage doubler out of a 555 timer, capacitors and some diodes. doesn’t put out much current though. Oh and an amplifier in oscillation for more current…. Someone in the comments around this site posted a link that lead me to those circuits.
During our testing, Qualcomm announced it began working with the UL and Wireless Power Consortium to officially bring its Quick Charge technology to Qi-compatible wireless chargers. Not only does Qualcomm want to do this because the industry is slowly shifting away from wired charging, but it also wants to make it clear which devices support Quick Charge and which do not (some devices falsely claim to support the technology now).

Abstract: Systems and methods for identification of a controlled-environment facility resident in possession of a contraband communications device capture or otherwise accept managed access data and/or contraband communications device assessment data for contraband communications devices operating in the controlled-environment facility. Controlled-environment facility resident call data for each resident of the controlled-environment facility is gathered from the controlled-environment facility resident communications system. Correlations in the managed access data and/or assessment data with the controlled-environment facility resident communications system call data are analyzed to identify each resident of the controlled-environment facility in possession of a contraband communications device.
Eventually, 5G will enter the picture with sub-6GHz capabilities, followed by mmWave. “For the out-car connectivity, such as 5G will need auto grade 1 at 28GHz, and 38GHz for high speed and high bandwidth communications. In the mmWave front, as CMOS geometries become smaller, Fmax becomes higher and able to serve higher frequency with better costs,” Liu added.
Bipolar transistors don’t need to dissipate power in their on state. The voltage drop is a result of the Base-Emitter junction when the supply voltage is connected to the collector. You can use the opposite polarity transistor and supply voltage to the emitter – that’s how LDOs work. In this config you need another transistor to invert the control signal and drive the main current transistor.
I use the BTS141 for a lot of projects. Probably its not good for higher frequencys but an easy to use all in one solution with enough power (and I have a lot of them in stock

The rising reliance on natural gas as a source of power is as noteworthy as the growth in wind. With Pickering Nuclear Generating Station closing down for good in five years and major refits at Darlington and Bruce reactors, power supply is in transition.
Abstract: A method of manufacturing a self-supporting, monolithic fuselage body, including engaging peripheral mandrel sections around at least one central mandrel section, placing uncured composite material on the mold surface, curing the composite material on the mold surface, and sliding the central mandrel section(s) out of engagement with the peripheral mandrel sections and disengaging the peripheral mandrel sections from the cured composite material without collapsing the mandrel sections. The peripheral mandrel sections each include a shape-retaining core of a thermally insulating material and an outer layer on an outer surface of the shape-retaining core. The outer layer has a coefficient of thermal expansion within the range of variation of that of the coefficient of thermal expansion of the composite material. A mandrel for layup and cure of a predetermined composite material in the manufacture of a monolithic fuselage is also discussed.
