i am given assignment by my teacher to design class A power amplifier that gives 3W output....
the circuit must be implemented both by series fed and transformer coupled techniques!!!!!
i have to:
1)implement the design problem on papers.......then find the efficiency also for both cases
2)design the circuits on multisim
Actually i dont know much about which transistor will be the best suited for this problem and will give output close to 3W....please suggest a transistor and also help me on how to start solving this problem as i am weak in designing !!!!
Also maximum efficency of series fed is 25% and of transformer coupled is 50%......... from datasheet i could get the dc load line and ac load line so that i can get values of Icmax,Vce(sat) and Hfe and determine the values of resistors...i am using voltage divider biasing........ so i need values of R1,R2(voltage divider network),Re,Rc and main is the value of Vin........(Vin is input signal) . i assume Vcc to be 18 volts!!!!!
