Introduction to RF Power Amplifier Design and Architecture
2020年3月6日 · Radio frequency (RF) power amplifier (PA) is an essential component of transmitter, which boosts the power of signal being transmitted over a long distance. The PA operates in large signal operation region where the inherent device nonlinearity will produce several distortions which reduces the spectral efficiency of transmission.
• Consists of two amplifiers −Envelope amplifier (provides VDD bias / current to RF PA −RF PA (operates in gain compression) • Envelope & pm signals must be developed, generally through digital methods • RF PA is inherently efficient due to operation in gain compression • Can be difficult to find a suitable envelope amplifier
