TV preamplifier circuit
Source: InternetPublisher:已注销 Keywords: capacitor coupling capacitor Updated: 2020/11/07
Shown is the pre-mid amplifier circuit of a television. The pre-mid amplifier circuit is composed of Qioi and xlol. Q[ol and bias components form
a common-emitter intermediate frequency amplifier. The intermediate frequency signal is added to the base of Qioi through the coupling capacitor
C]ol. After amplification, it is output by the collector, and then added to the surface acoustic wave signal
through the coupling capacitor C103. The input end of the filter XjoJ (the coupling capacitor has the function of blocking DC). The inductor Lioi
is connected in parallel with Qioi's collector load resistor R106, and L10l's high impedance to high-frequency signals is used to compensate for the high-frequency characteristics of the pre-amplifier.
