Radio circuit diagrams electronics projects for radio transmitter, radio receiver circuit, rf amplifiers, rf boosters and some other related RF circuits like: fm antenna booster, microwave transmitter and wireless modules.
This radio remote transmitter circuit works in UHF-FM radio band and can be used for shareholders different systems like garage doors, alarm systems, etc..
Using electronic diagram below can be design a UHF amplifier circuit useful in situations where the TV signal is weak. The UHF amplifier circuit has a gain of 10-15 dB in a frequency range between 400 and 850 MHz.
To obtain optimum performance and good reliability, the PCB tracks should be covered with tin.
At each disc capacitors C4, C5, C8 and C9, by one of the girls is glued directly on board.
All other terminals are to be cut as short as possible and will use SMD components.
