Hi All,

I've been checking class E amplifier literatures, but couldn't find anything mentioning how to generate the input signal.
Normally, only a 50% duty cycle is presented to explain circuit operation.

My application is based on CDMA, QKSK. So how do I use the I and Q to get my input signal for class E ( or in that case, for any kind of switching amplifiers ) ?

Thank you.

Best Regards,
Linfei
