Pick a Plug ’n’ Play Linearizer for Your 5G RF Power Amplifier
In this design solution, we present the features and benefits that 5G telecommunications technology promises to bring and the associated demands that these will place on RF power amplifier (PA) designs. We then review the most commonly used PA linearization techniques, assessing their suitability to meet these demands before presenting a low-power linearizer IC with the potential to greatly simplify the design of PAs used in 5G network applications, while also reducing power consumption.

How to Build a Cooler, Denser ASIC Mining Rig
Cryptocurrency and other blockchain technologies are computationally intensive. Current blockchain mining rigs rely on hundreds of dedicated ASICs that consume kilowatts of power for computation. Converters used to power the ASICs must be space- and power-efficient to maximize density and minimize heat generation. After a quick review of this new class of applications, we propose a two-phase buck converter with a coupled inductor as the ideal solution to power the ASICs.

How to Fast-Charge your Supercapacitor
Supercapacitors (or ultracapacitors) are suited for short charge and discharge cycles. They require high currents for fast charge as well as a high voltage with a high number in series as shown in two usage cases: an automatic pallet shuttle and a fail-safe backup system. In these and many other cases, the fast charge is provided by a flexible, high-efficiency, high-voltage, and high-current charger based on a synchronous, step-down, supercapacitor charger controller.
