Drain Efficiency is a method of accessing efficiency in Power Electronics. Drain Efficiency gets its name from FET devices, in which the primary terminal where DC power is supplied is the drain. Drain Efficiency is the ratio of output RF Power to the input DC Power. In regards to amplifiers, efficiency is the ratio between the output power to the DC input power, and thus referred to as drain efficiency. Drain Efficiency is represented as a percentage whereas the Output Power and DC Power are represented in Watts(W).
