Power Amplifiers for Communications

Peak E ciency Power Added E ciency (PAE) is a popular metric. P out is the output power, P in is the input power, and P dc is the DC power consumption of the PA For high power gain systems (G p), the e ciency approaches the drain drain e ciency ( d), or for a BJT, the \collector" e ciency, or simply the e ciency of the last stage
