simple booster tv schematic diagram


Posted on Feb 6, 2014

This is circuit that can be used to strengthen the RF signals from a television antenna work at UHF frequencies in the range 450-800MHz. It has a gain of around 10dB and is suitable for boosting weak TV signals The tuned circuit comprising the 15nH inductor and 2. 2pF capacitor resonate in the center of the UHF band. The 2. 2pF capacitor may be Exch

anged for a 4. 7pF or a Trimmer capacitor of 2-6pF to improve results. The approximate frequency response is shown below. N. B. This is a simulated response using the TINA program produced by using a swept input 20uV swept over the frequency range 400-800MHz. Output was measured into a 1k source and the frequency generator has a 75ohm impedance.
