Understanding RF Power Amplifiers

Basic Concepts of RF Power Amplifiers RF power amplifiers (RF PA) are a crucial part of the transmission system, and their importance is self-evident. In the front-end circuit of the transmitter, the RF signal power generated by the modulation oscillator is very small and needs to be amplified through a series of stages (buffer stage, … Read more

In-Depth Analysis of CMOS, FinFET, SOI, and GaN Process Technologies

The invention of the vacuum tube was a significant driving force in the development of the electronics industry. However, after World War II, the need for a large number of discrete components significantly increased the complexity and power consumption of devices, while their performance continuously declined. One example is the Boeing B-29, which consisted of … Read more
