Radio circuits electronic circuits design projects
Radio circuits electronic circuits design projects and schematics various transmitters, receivers, rf amplifiers, rf boosters and other similar radio circuits.
This antenna selector circuit diagram is designed using common electronic components and is very useful when are used many external antennas .
This antenna selector circuit diagram uses PIN diodes which eliminate disadvantages of mechanical switches (especially at high frequency current) PIN diodes can be used which are ideal for this purpose.
This antenna selector circuit diagram electronic project is designed using common electronic components and allows switching between two FM antennas via a logic signal.
This UHF amplifier circuit electronic project can be 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.
