Building an 80-Meter Class E/F RF Amplifier...
Jeff,
Your 80m amp inspires several questions...
- Is the purpose of R8/R9 to protect U8/U9 from excessive peak current, or to mitigate ringing, or...?
- Did you find the symmetry adjustment (R3/R6) necessary or was it more just-in-case?
- Did you ramp up/down the PA ON signal to minimize key-clicks? ?I've been thinking of doing something similar to minimize clicks when the PA turns on/off.?
