Embedded Resistor PCB: Thin-Film Resistive Foil for Millimetre-Wave Boards
Embedded Resistor PCB: Thin-Film Resistive Foil for Millimetre-Wave Boards At millimetre-wave frequencies, the humble chip resistor runs out of road. Not because its resistance drifts — because its pads, solder joints and return path become significant fractions of a wavelength,…
