RF PCB design is one of those areas where the rules you learned for digital boards start to actively work against you. Trace impedance, return path continuity, component placement, and grounding all become first-class concerns rather than afterthoughts — and getting hands-on walkthroughs of real RF layouts is surprisingly rare on YouTube, especially from smaller creators willing to slow down and explain their reasoning.

This video takes you through the design of an RF power detector, a circuit that converts an incoming RF signal into a proportional DC voltage. These show up everywhere from transmitter power monitoring to received-signal-strength indicators, and they're a great teaching vehicle because they force you to think about signal integrity from the antenna port all the way to the ADC.

The walkthrough is done in Altium Designer, so viewers get exposure to a professional-tier PCB tool rather than the KiCad tutorials that dominate this space. Expect discussion of controlled-impedance traces, ground plane strategy, decoupling around the detector IC, and the placement decisions that keep RF energy where it belongs and out of the DC output path.
