Radio frequency skin tightening (RF) is an aesthetic technique that uses RF energy to heat tissue and stimulate subdermal collagen production in order to reduce the appearance of fine lines and loose skin. The technique induces tissue remodeling and production of new collagen and elastin. The process provides an alternative to cosmetic surgeries such as tummy tuck. | The Body Bar | Facebook

Radio Frequency engineering is one of those fields that humbles even experienced engineers. Once you reach frequencies above a few hundred MHz, the rules change rapidly. Traces stop behaving like wires, impedance becomes a moving target, and your PCB layout quietly decides the fate of your entire design. This article, the first in a multi-part series on “Mastering RF Engineering,” by Mouser Electronics, explores how RF technology is designed, built, and tested, highlighting the principles, compo
