        Some tips for when designing hardware and PCBs with simple RF sections and components. These concepts have aided me well when designing 4-layer embedded systems PCBs.<br><br>Topics: critical trace lengths, stackups, controlled impedance traces (microstrip, stripline), impedance discontinuities due to wide pads, clearances, bias tees.
