 Class E Power Amplifier Questions (Read 453 times)
 blue111 Community Member Offline Posts: 81 Class E Power Amplifier Questions Jul 17th, 2020, 6:18pm   I have some questions about Class E Power Amplifier1) From page 183 of Advances in Electronics, Communication and Computing ,(a) why Maximum output power is calculated as 0.577 Vdd2 / R ?(b) What does it mean by Vgs (min) = 5% of Vdd = 0.09 V and Vgs (max) = 7% of Vdd = 0.126 V. Therefore Vgs value will be in between 0.09 and 0.126 V ? 2) From Figures 4 and 5 on page 3 of A Class-E RF Power Amplifier with a Novel Matching Network for High-Efficiency Dynamic Load Modulation ,(a) how to determines values of all the values of capacitors and inductors of both the input and output impedance matching networks ?(b) how to use Spice software to simulate if it does not have smith chart plotting capability ?(c) How to bias the two pull-up inductors (Lrf, Ldriver) and two resistors (Rb1, Rb2) ?(d) How does the proposed digitally-controlled matching network works ?
