Activities : On this week, i have to find the example of RF Transmitter and RF Receiver circuit. I have to know how the circuit work and the list of component. I also have listing the equipment may use to make the circuit.
Analysis : The details are shown below:
CIRCUIT AND COMPONENT + EQUIPMENT USE:
RF Transmitter & RF Receiver circuit
This is RF transmitter circuit diagram. For this
diagram, from switch, there is a connection to LED. We use 9volt dc supply. At
this circuit, we use rf choke to cut down on radio frequency interference, and
as a prevention of malfunction of component. This circuit also includes the RF
coil which is the most critical part of this circuit. This RF coil acting as an
antenna. This connection of this coil is very sensitive.
The most critical part in this receiver
circuit is the coil which works as an antenna and the pre amplifier that works
to increase the size of the bandwidth. The relay will sound when it detected a
signal from transmitter.
