Simple Cable TV Amplifier Circuit

Posted on Feb 6, 2014

This cable tv amplifier circuit is a rf amplifier designed to be quickly installed between two coaxial cables. Both input and output impedances are compatible with 75 © cables. The main amplifier si T1 transistor, T2 is working as an emitter follower. The feedback bias is determined by R3 and R4. Because of the high frequency limit of transistors
