RF Transmitter Explained

RF transmitter is also called a radio frequency transmitter. This is an electronic device that transmits radio frequency that is composed of different components with different functions. The radio communication system is composed of two circuits to transmit a radio signal and another two circuits to receive the transmitted signal all four of these circuits are tuned in with the same radio frequency. The transmitter is an electronic device with the use of an antenna to produce and send electromagnetic signal for radio, television, and other telecommunication gadgets.

The transmission of this kind of signal involves many parts that serve several functions as a group. These groupings are called blocks that have general role in the transmission process. Each of these blocks has a major role to complete the system of sending radio frequency or signal. Before, a circuit is composed of many electronic parts such as diodes, capacitors, and lots of resistor. These are grouped to perform a certain task involved in the transmission. This circuit can also be considered as a single block. Then, another set of these devices with different measurements or units of their role are also grouped to perform a different function that contributes much in order to fully accomplish the objective in transmitting a radio signal.

The last section of the transmitter is the antenna which is also composed of several parts. However, many misinterpret that only the antenna is the transmitter. The entire radio frequency transmitter has a number of these circuits to produce and send radio waves through the air. While on live broadcast, the term "on air" of radio and television stations was derived from these radio waves being sent through the air. To avoid further misinterpretation, and simply comprehend, the term "on air" means broadcasting on time live conversation and events as they occur. These radio waves or frequency, otherwise known as signal which then will be received by another electronic device. This gadget may be a television, a radio, or another telecommunication device.

The time came when transceivers are introduced to the market. These consist of a built-in radio transmitter on the same item that also receive signals that are identical. At first, the hand-held radio was used but can only be applicable for short distances only. Then the primitive model of the cellular phones existed. These had an application limited to voice calls only but with the use of series of transmitters all over. Now, as technology advanced, cellular phones can even send a video clip through satellites that also serve as transmitters located in space nearby. At this age of the internet, even the high-tech computers of today, still relies on the concept of the system of the radio frequency transmitter.
