DC Stop / DC Block

Posted by Perception System Tuesday, September 13, 2011 0 comments

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 with high isolation between the two ports.

RF Power Amplifier – Enhances Your Signal Strength and Efficiency

Posted by Perception System Sunday, September 11, 2011 0 comments

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 demanding devices in this field.

Why RF Amplifiers are in High demand?

RF amplifier is a one kind of electronic amplifier, used to modify signal of low-power radio-frequency (RF) into a higher signal of a significantly power, in general driving a transmitter antenna. It is generally used to get high output power compression, good return loss at the entrance and exit, optimal heat dissipation and high efficiency.

So if you are looking for purchase RF Power amplifiers, then I suggest you SHIREEN NIC. It is a leading company of USA, which provides designs, develops and manufactures components and systems for the Broadband Wireless, SCADA, Military and Telecommunications industries.

We also provide Cat5e Shielded, Coax cables, rf converter, high power amplifiers, RF Amplifiers, LMR400, cellular repeater, etc. Our solutions include everything from “mission critical” components for military communication systems to increasing the power of WiFi installations.

Coax Cables - A Look Into Its Various Components and Principles

Posted by Perception System Thursday, September 8, 2011 0 comments


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. Of course, you must also see through the various components of the design in order to ascertain the industrial product's performance. Apart from looking at product parts, you must also scrutinize the processes behind it.

Standard designs for coaxial cable systems

The design of the coaxial cable is important to the proper functioning of the device. The design dictates the efficient transfer of energy from one device to another. The most usual parts are the signal wire, insulation, shielding and sheath.

Copper is the standard part used in forming signal wires. Strands of copper may be utilized while some opt for a more solid output. This is usually situated at the core layer of the cable and is known to be relevant in the strength of signal transmission.

The insulation is the part that covers the signal wires. This often comes in the form of dielectric wrappers constructed out of polyethylene, Teflon and foam. Protecting the insulation is another part known as the shielding. This part is created out of aluminum or mesh. Some industries utilizing the coaxial cable do not always require the presence of the shielding. Last but not the least is the part otherwise known as the sheath. This is the outermost layer of the coaxial cable. This one is used to secure the cable from physical interference or disturbance.

Coaxial cable connection processes

The proper functioning of the coaxial cable depends upon its designs. If you want an effective transmission gadget, you must look into basic principles in order to make the gadget work. An example of a principle to look forward to deals with the matching of impedance between the cable and the device. Look for the gage rating also to know whether certain cables or parts can be best suited to the coaxial cable or not.

Diameter of the coaxial cables must also be thought of properly. The longer the cable is, the better the power that makes it work. Some manufacturers use hollow designs to reduce the cost connected to the coaxial cable design and to assure that it can be reshaped and bended for better processes.
