Hello!
I am designing a Class E amplifier. Its input signal is a BPSK signal below of around 4vpp and I need it to be amplified at least 15.4 dBm.
Furthermore, it needs to be able to drive a 50 ohm load. I used the Class E component calculator to solve so that R = 50 because that's my given load.
This is my schematic:
but the result named [Output] is distorted. In fact, it even distorted my BPSK signal.
I was thinking if maybe my transistor was the problem, but I've tried most of the transistors here and it still didn't work. Do you guys have any idea? I chose Class E because it's the most convenient because of the calculator (and because it can achieve 100% efficiency theoretically and I will only simulate anyways), but maybe it's impossible to achieve my goal with Class E? Or maybe the transistor is the problem?
Thank you very much!
