This is a actual simple cable TV amplifier application two transistors. This amplifier ambit is a lot of acceptable for cable TV systems application 75 Ohm coaxial cables and works accomplished up to 150MHz. Transistor T1 performs the job of amplification. Up to 20dB accretion can be accepted from the circuit.T2 is active as an emitter addict to access accepted gain.Notes.
- The circuit can be assembled on a Vero board.
- Use 12V DC for powering the circuit.
- Type no of the transistors are not very critical.
- Any medium power NPN RF transistors can be used in place of T1 and T2.
- This is just an elementary circuit. Do not compare it with high quality Cable TV amplifiers available in the market.
