Hello,
I am making the 4 Watt Power Amplifier for TRF7960 according to the datasheet "HF Power Amplifier (Reference Design Guide)" from TI official website.The problem is that
there is a self-oscillation at about 12.8MHz shown in my oscilloscope as soon as I give in a DC power and the amplitude can rich to 3 times of the needed signal.I checked the
circuit and find out the problem may probably related to " Rx phase shift" part but not sure for this.Have anyone met with a similar problem?Is there any possible ways to solve
this problem?
Appreciate for reading my questions very much and thank you in advance.
