High Power Amplifier Block Diagram. That is why in an electronic system a voltage amplifier circuit always precedes a power amplifier circuit as shown in block diagram of amplifier circuit figure 1. For an rf power amplifier to function correctly it must be supplied with a load.
An amplifier is an electronic device used to increase the magnitude of voltage current power of an input signal. That is why in an electronic system a voltage amplifier circuit always precedes a power amplifier circuit as shown in block diagram of amplifier circuit figure 1. Use a well regulated and filtered 12 v dual power supply that is able to provide at least 2 a continuous current.
With ordinary high nfb power amplifiers high input impedances high z in say above 10kω to 1mω or more are readily attained.
Different power amplifier stages are shown in the block diagram below. Power amplifier circuit is meant to raise the power level of the input signal. Use a well regulated and filtered 12 v dual power supply that is able to provide at least 2 a continuous current. Figure 1 shows the block diagram of high power rf amplifier including 6 1 8 coaxial transmission lines such as circulator loads directional coupler and an rfq.
