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...
Shireen Inc. has rolled out an optical repeater module designed for WCDMA networks. The RF module is used to monitor and control optical output power, LD bias current, received optical power, input and output RF signal power of Master, received FSK signal power and RF Gain control through the MCU. It is also used for RoHS compliant products.
The optical module for the repeater includes a linear analog PD with high sensitivity and a high power DFB laser, a low noise, linear RF amplifiers, as well as built-in Bi-Di components...

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...
