Q: In radio frequency (RF) circuits used for portable applications, power efficiency is extremely important. For this reason, Class C power amplifiers are used wherever practical. There are some limitations in using Class C amplifiers, as we discussed in class. Identify these issues. Another consideration for a power amplifier is efficient coupling of energy from the amplifier to the load. This generally requires an impedance matching network. Two circuits that could be used to match the amplifier output impedance to the load impedance. Ignoring tunability or component sizes, which is likely to be the best choice for a Class C amplifier? Why?
