RF Micro Devices has introduced a portfolio of push-pull amplifiers designed for multiple catv infrastructure applications. The CGA/CGR product portfolio includes the CGA-1518Z and CGA-7718Z ...
Despite recent improvements in the performance of RF LDMOS field-effect transistors (FETs), temperature drift and aging continue to affect the efficiency and linearization of power amplifiers using ...
With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...
Unlike power switching FETs, RF FETs are designed to work best in the linear region of operation to maximize power gain and minimize distortion, whereas power switching devices are optimized for ...
