ABSTRACT
High frequency signal resonance amplifier was widely used in telecommunications . Broadcasting equipment and so on. We can use, LC loop resonance frequency selective parallel resonant frequency amplifier , thus the particular signal. Transistor amplifier with voltage gain of emitter, output voltage and input voltage, frequency characteristics of the poor performance, suitable for low and middle level of multi-level amplifier circuit, using two levels of signal tuned circuit will original weak signal, and by using the LC 100 times parallel resonant circuit will be elected signal. The technical indexes of amplifier and test method, the impact of distribution parameters of the circumstances about circuit performance. Small signal resonance frequency amplifier, characterized by the main performance indexes, the harmonic resonance frequency and voltage magnification Av0 amplifier pass band BW and selective rectangular coefficient usually.
Keywords triode LC resonant quality factor pass band rectangular coefficient.
