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 ...
Gallium nitride (GaN) RF transistors have traditionally been depletion mode, making them difficult to bias. High frequency enhancement mode transistors, such as the EPC8000 series eGaN FETs from EPC, ...
The Class E power amplifier can be turned into an efficient, tuned-input, tuned-output (TITO) oscillator with the addition of a tuned circuit at its gate. The oscillator/amplifier has a power-added ...
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 ...
