Application Note: Wireless -- Decoupling high-frequency signals from a DC supply

From 5G systems to radio and antenna applications, wireless communication accompanies us throughout our daily lives, so the demand for universal high-frequency amplifiers is correspondingly high. By selecting the optimal passive components, the transmission characteristics of the amplifier can be improved during development. A well-designed layout further improves RF performance. The aim is to transmit both RF signals and the DC supply on a single line without interference or cross-talk. A key component is the inductor for decoupling the RF and DC supplies.

Smartwatches, fitness trackers, and other Internet of Things devices could get a significant boost to their battery life thanks to new, environmentally friendly energy research from the University of Surrey's Advanced Technology Institute (ATI) in the UK and the Federal University of Pelotas (UFPel), Brazil.

In a paper published by the journal Nanoscale, a research team has demonstrated how a supercapacitor can be efficiently manufactured into a high-performance and low-cost power storage device that can be easily integrated into footwear, clothing, and accessories.

Professor Ravi Silva, Director of the ATI and Head of the Nano-Electronics Center at the University of Surrey, said, "Supercapacitors are key to ensuring that 5G and 6G technologies reach their full potential. While supercapacitors can certainly boost the lifespan of wearable consumer technologies, they have the potential to be revolutionary when you think about their role in autonomous vehicles and AI-assisted smart sensors that could help us all conserve energy. This is why it's important that we create a low-cost and environmentally friendly way to produce this incredibly promising energy storage technology. The future is certainly bright for supercapacitors."

A supercapacitor is a means to store and release electricity, like a typical battery, but it does so with far quicker recharging and discharging times.

In the paper, the research team describes a new procedure for the development of flexible supercapacitors based on carbon nanomaterials. This method, which is cheaper and less time consuming to fabricate, involves transferring aligned carbon nanotube (CNT) arrays from a silicon wafer to a polydimethylsiloxane (PDMS) matrix. This is then coated in a material called polyaniline (PANI), which stores energy through a mechanism known as "pseudocapacitance," offering outstanding energy storage properties with exceptional mechanical integrity.

The team's enhanced, wafer-thin supercapacitor retains most of its capacitance (the amount of separate electric charge that can be stored) after numerous cycles at different bending conditions, demonstrating its robustness, longevity, and efficiency.
