Coax Cable is a type of wire that consists of a center wire surrounded by insulating materials and then a grounded shield of braided wire. Coax cable is a cable type used to carry radio signals, video signals, measurement signals and data signals. The shield minimizes electrical and radio frequency interference.Coax cabling is the primary type of cabling used by the cable television industry and is also widely used for computer networks, such as Ethernet. It is more expensive than standard telephone wire; it is much less susceptible...

Efficiency and make of a RF amplifier determines the class it belongs to. Class E amplifiers are considered to be the best as they deliver significantly higher quality signals as compared to other class amplifiers. Transistor in Class E amplifiers works as a switch with a similar on/off function. Load network mechanism molds the current voltage and waveforms in a manner so as to avoid high voltage and current occurrences to limit power spread especially when the transistor switches on and off.When the same transistor at the...

Type of coax cables used affects their use and longevity. Inferior quality cables can cause greater damage when used commercially on a distribution system. Hence it is important to select the right quality cables to ensure that you do not face any problems in future because of their faulty make. However it becomes really difficult to judge the quality of the cable just based on their manufacturing details as most of the times quantifiable data regarding their performance is not available.To make things easier you can always...

Most of the wireless systems are built using voltage controlled oscillators to control the movement of the frequency from source to unit. As the name hints two oscillators are used in dual-conversion systems. While one fine tunes all the input channel frequencies other functions at a pre-determined single frequency. They can be used either as an IC, module or discrete component circuit however they are more frequently used as part of an IC or a discrete circuit due to the price constraints.Discrete-feature of voltage controlled...

RF power amplifiers fall into different classes based on their peculiar endurance, linearity and distortion levels. Class E is one of the finest types of RF power amplifiers used to achieve greater efficiency. What sets them apart is that the transistor in Class E amplifier acts as a switch with ON/OFF function. To avoid recurring high voltage and current fluctuations, load network controls the voltage and current waveforms in such a manner that power dissipation is lowest at all the times especially in between switching transitions....

For those who are less familiar with RF amplifiers, it is a device through which the input can be amplified for a much intensified output. Sound signals by themselves are really weak but can be made stronger using an amplifier. They come in many different types based on their design which indicates the circuitry within it and are represented through classes A, B, AB, C and D.Class A: Very low distortion, highly inefficient is how you can define class a amplifiers. Distortion level in an amp depends on the transistor; transistors...

Performance of a high power RF amplifier depends on its resiliency to provide outstanding performance for a much longer period of time that is most likely to be more than 20 years. Resiliency of an amplifier is termed as ruggedness in the electronics world. Most of the amp manufacturers consider ruggedness as one of the most crucial aspects of their design process.From times known silicon based technologies like bipolar or LDMOS have been...

Cell phones keep you connected everywhere you go, however they have a limitation and that is they need appropriate signals to be able to connect you to others. When the signals are low or are not available then it is nothing less than an empty device of no use. You feel frustrated in situations like this, but now no more because now we have cellular repeater, a cell phone signal amplifier. What is a cellular repeater? As commonly defined in the wireless telecommunications industry cellular repeater is a type of BDA (Bi-Directional...

Cables – they are everywhere we use them in one or other electrical appliances but what is special about Coax cables. An easy paradigm to understand them would be human body - just like arteries carry blood to different parts of our body cables are used to carry electricity needed to run different electric appliances. Coax cables are one among the many different types of cables available in the market. Though mainly used in computers they are also used in video and radio electronics. Its core objective is to transform electricity...

Voltage controlled oscillators are commonly abbreviated as VCO. The VCO's are electrical circuits that yield an oscillatory output voltage. A VCO is an oscillator whose output frequency is proportional to the applied input voltage. The parts of a VCO circuit has a LC tank circuit with an inductor(L) and a capacitor(C) along with one or two transistors accompanied by a buffer amplifier. A VCO gives a periodic output signal where the output signal parameter is directly related to level of input control voltage. The center frequency...

There are many choices for broadband service providers and the technologies they offer. Cable Television Systems throughout the world use multiple network architectures to deploy their services. One of the most prevalent ones is referred to as HFC (Hybrid Fiber Coax) this is known as a closed system network. That is to say, the signals are not transmitted through the air. They are sealed within a combination of fiber optic and coaxial cables. The technology has been around since the early 1980s. It has undergone major...

You are often suggested to buy RF amplifier when you are out there planning to buy a radio. Know why? Because amplifiers are simple devices which enhance the sound quality you receive from audio devices. RF (radio frequency) amplifiers are especially designed to go with radios. They receive varied input signals in the form of current, voltage or others and transform them into output signals with larger amplitude based on the input signal.Though both the input and the output devices use different circuits, signals received and...

You need a cell phone signal booster. How Cell Repeaters Work Cell repeaters, also known as cell amplifiers, cell extenders or cell boosters,...

DC Stop / DC Block This DC stop prevents DC voltage from being shorted in power over coax systems, where mast head amplifier is not used.  Typically the mast head amplifiers are fed power over coax via Bias T, feeding power to multiple antennas in 900Mhz and 1.8GHz bands. This DC stop is needed if power is fed up the tower without using amplifier at any antenna.   The unit provides excellent loss & VSWR characteristics...
