RF Amplifiers – How They Deliver Radio to the World

Signals – whether they’re for radio, TV, cell phones or any other application – are really nothing more than electrical currents. The term RF stands for radio frequency… but is applied in a couple of different ways.

In the technical sense, a radio frequency (RF) signifies rate of oscillation, which occurs anywhere from 3kHz to 300 GHz. For transmitting radio signals though, it isn’t as simple as just having an antenna and minimal equipment.

When radio signals originate, they’re generally very weak electrical currents, especially if it’s from some sort of microphone device like walkie-talkie or radio station system. These original signals are often times too weak for transmission over a long distance. Therefore, to transform this weak signal into something powerful to transmit over an antenna, an RF amplifier is used to boost the signal.

The process for transmitting signals for radio or other applications occurs in several stages in fact. In each of the stages, a signal is modified in some way to produce a desired output. Broadcast signals in fact are a collection of different “signals”, each with its own role in the final output. In the case of radio, this can include speech or music.

The RF amplifier essentially boosts each signal equally to produce a clean, linearly amplified signal which is then transferred to a system with much higher power. An RF amplifier in fact takes distortions in a radio signal and distorts them even further. Therefore, a big job of the amplifier is to ensure the signal is given maximum strength with as little distortion as possible.

Linearity, or the ability to amplify all parts of a signal by the same amount (… to ensure all signals are amplified equally), is the core element of an RF amplifier.

Within the amplification process itself, the triode – or a diode with an attached control grid – is the device primarily responsible for signal enhancement. The attached control grid regulates the electric charge flowing through the diode. By applying small voltage variations, the triode can make significant changes in the strength and behavior of the current.

In radio broadcast, information transmitted through radio frequency takes the form of speech or music and is called “modulation.” Amplitude modulation, or AM radio, is the earliest and simplest form of radio frequency modulation. It’s simple in that there’s essentially only one stage where an amplifier only has to vary the power output of an RF stage by varying the input signal.

Frequency modulation (FM) was developed in the 1930s, and while it produces a much cleaner signal, it’s a bit more complicated than AM.

Today, RF amplifiers are used in a variety of areas, including AM/FM radio, TV, radio towers, walkie-talkies and even in every cell phone and cell phone tower.

It’s safe to say that an RF amplifier constitutes a critical part of transmitting and receiving signals. Without them, radio signals would not be able to travel that far.

Think about it this way – if a DJ is speaking at the radio station and there was no way to boost the strength of the waves carrying his voice, then the only people that will be able to hear what he’s saying are ones standing in the room, or otherwise within hearing distance.

Solar Generators – The New Leader in an Energy Starved World

Solar generators could be our way out of the trench of negative facts we read every day. Increasing global demand for power, daily warnings about our environment, ever increasing carbon gases emitted from fossil fuel. The world is gradually heading towards a severe energy crisis that we can not ignore any longer. Whether you are seeking to stand on your own two feet amid this energy crises or are just seeking a more environmental alternative, solar generators are the essential key to your long term energy independence.

A solar generator can benefit the home in a variety of ways. Depending on the size, it can allow a homeowner and family to remain unaffected in the event of a power failure. Are you protected? When brown outs, black outs and the like come to your front door, how will your check book handle the mountainous rise in energy rates?

A portable solar generator can completely replace a light-duty gasoline generator in many applications. These are light weight, energy efficient and produce a tremendous amount of electricity compared to the cost. The market for solar is only beginning and is going to be the leader in the backups of household energies.

Solar generators can now do the work that diesel, gasoline, and propane generators used to do. Powering road construction signs, any lighting application and general power backup – solar generators are provoking themselves worthy on the energy market.

An energy producing and saving device in conjunction with a typical 20 watt solar panel receiving 5 hours per day of full sun, would generate 100 watt-hours of energy. This energy can be stored in the form of batteries as well as used in conjunction with generators to provide a highly beneficial power reserve.

With solar generators you can generate real, usable power in your very own home (or wherever), and it'll cost you less than a typical generator with a long lasting life of renewable energy. Common applications for such a device are being used in mobile homes, construction sites and camping applications.

Creating a solar generator is a simple process. Using parts easily attainable from your local stores, you can make a small power device for $ 250 to $ 300. There are multiple resources and literature available online for your reference in developing your own alternative energy source.

Once you obtain the parts for your generator, which include a small solar panel, a battery, a DC input and an AC inverter, assembly takes about an hour to complete. Again, this is not rocket science, but it will require a little due diligence on your part to insure you are building the device to maximum efficiency for a long life of renewable energy.
