Those who live in areas with limited cellular coverage are all too familiar with the tell-tale signs of poor cell phone reception: dropped calls, poor voice quality, weak signals and poor battery life. In recent years, as cell phone usage skyrocketed, those in rural areas found themselves limited to just a few carriers with spotty coverage in their area. Then, along came 3G cell boosters. Cell phone signal boosters for the 850MHz and 1900MHz bands have proliferated the market, offering improved voice quality, fewer...
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...
Now-a-days, the demand for frequency converter or frequency charger has been increased in many industries. The reason for this it’s fairly obvious, industries around the world need energy-saving devices in a variety of industrial applications and the frequency converters are of great help to solve the problem considerably. In a couple of years, the markets of frequency converters are expected to increase by fourfold its present size.Frequency...

You're tired of experiencing poor cell phone reception, dropped calls and poor voice quality. You get some reception outside your home or office, but as soon as you step inside it seems to magically disappear. Your phone is constantly scanning for a signal, so your battery dies much faster than it should. You've double checked your phone and called your carrier, all to no avail.
You need a cell phone signal booster.

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...
Amplifier is a device used to increase the dimension of a signal. This is a one kind of relationship between input & output amplifier, which is signified in terms of the input frequency known as transfer function and the volume of output to the input is called in reinforcements, usually measured in decibels.These conditions are best suited to "electronic amplifier." A unit of the amplifier is signifying as voltage or current. There are various amplifiers available in the market, but RF Power Amplifier is one of the most...
Coax cables are used in radio frequency transmission and in applications where receivers, transmitters and antennas are used. Part of its basic tasks is to strengthen signals of particular types of gadgets. The device works in processes dictated by coaxial technology.
Coax cables come in several designs as well. Knowing about the components of these designs will give you an idea of how it actually looks like....
