Eltronicschool. - For you who want to develop your TV cable booster amplifier, in here we will show you 2 kinds of electronic circuits schematic for TV Cable Booster Amplifier. We think this schematic will help you to receive TV channel report when you difficulty to receive it maybe because of signal deflecting, reflecting, etc.

Description
From Figure 1 above show us that this is a schematic of a cable TV signal booster amplifier circuit which can be used to amplify or boost the signal of cable TV system. Use 75 Ohm coaxial cables at the input and output of the circuit and fit the circuit in a metal case. The bandwidth of the circuit is up to 150MHz. Transistor Q1 is used to amplify the signal and Q2 is working as an emitter follower. The circuit will provide gain of 20dB or more. The current consumption of the circuit is only 20mA.
From Figure 2 above show us that this is a very simple cable TV amplifier using two transistors. This amplifier circuit is most suitable for cable TV systems using 75 Ohm coaxial cables and works fine up to 150MHz. Transistor T1 performs the job of amplification. Up to 20dB gain can be expected from the circuit.T2 is wired as an emitter follower to increase current gain.
