Broadband Amplifiers

The most popular type of broadband amplifier found in the marketplace today is the compact amplifier platform. They include a variety of RF amplifiers that thoroughly address the very diverse nature of today’s broadband networks. Broadband amplifiers are specifically optimized for both trunk and distribution applications. They are known to provide extreme reliability and are now used in combination with this user-friendly layout.

The majority of broadband amplifiers will need to be configured with diplex filters and forwarded into stage pads and inter-stage equalizer. This will ensure that optimal performance is achieved. Broadband amplifiers will actually enable a reverse bandwidth of more than 65 MHz. You should find that all broadband amplifiers will utilize an orange plug-in three pin attenuator pads. These pads make it very easy to replace the amplifier and are known for their user-friendliness.

One of the first major uses of broadband amplifiers was the ability to maintain instant communications within the Armed Forces. They specifically designed a miniature broadband power amplifier with greater than a decade bandwidth or 30 – 512 MHz. This is the specific bandwidth that is required for all band transceivers. It will cover a tactical ground and air frequencies in addition to civil telecommunication frequencies and even the frequencies of our allies.

There is also a direct correlation between audio frequency (AF) and broadband amplifiers. These are sometimes known as valve amplifiers. You will find the use of valves remain extremely widespread in the use of guitar and high-end audio amplifiers. This is mainly due to the sound quality that they will produce and this is definitely preferred by many users. Valve amplifiers have slowly become obsolete for many other applications and this is mainly due to the cost effectiveness and the advantages of the transistor. They weigh a lot less and produce far less heat than a broadband or valve amplifier.

For many years the main driving application behind audio amplification was telephony. One of the main issues for the telecommunications industry was a technique of multiplexing numerous voice lines into a single cable, or keeping them all at different frequencies. A broadband or valve amplifier gives the advantage that it could amplify many calls all at once. This, of course, was also extremely cost-effective.

Nowadays the main application for valve and broadband amplifiers is for the use in a high-end hi-fi musical performance. They can be used for electric guitars and electric basses. You may be aware that these applications have very different requirements regarding distortion which can obviously result in many different design compromises. However it should be known that the same basic design techniques are similar and applicable to all broadband amplifier applications and not just audio.

There is currently research still being undertaken on a high-performance power amplifier that is able to accommodate a wide range of frequency bands. One of the more recent series of broadband amplifiers is the BBA series, which can best be described as a family of low-cost and high-performance broadband RF amplifiers. They are specifically and ideally suited to a wide range of amplification and buffering applications. This current new breed of broadband amplifiers is far more sensitive than its predecessors and provides a far greater range. This specific new range of broadband amplifier can dramatically boost the output power of a transmitter to much higher levels and will also provide a significant increase in range. This increase in range should only be used where legally appropriate.

One of the most recent advances in broadband amplifying technology was created by Cornell University researchers. They created a broadband light amplifier on a silicon chip, which is being hailed as a major breakthrough in the quest to create photonic microchips. You will find that these types of microchips that will produce a beam of light travelling through microscopic waveguides will actually replace electric currents travelling through the microscopic wires.

The specific new type of broadband amplifier uses a phenomenon that is known as four wave mixing. This is where a signal will be amplified or “pumped” by another light source inside a very narrow waveguide. The waveguide should be a channel that is only 300 x 550 nanometers wide, which is actually smaller than the wavelength of the infrared light traveling through it. Both the photons of light within the pump and the signal beams are extremely tightly confined to allow for the transfer of energy between the two beams.
