Hello friends
1-in some RF transistor i see that high power gain for instance:GPe>3db
what is the meaning of GPE according to db?(could you give me an example?)
2-i want to create hartly or collpits oscilator with transistor with 100Mhz frequency.what is the best transistor?(how can we choose it?)
3-in telecommunication circuit write on their brands for example 10W(for transmitter) how did they calculate it? for example if i have a emitter common transistor if IC=1A and VCE=10v my transmitter has P=10W power to transmit wave?
