Advanced Radio Frequency Products
Radio frequency components are used throughout communications and other wireless network systems to exchange information over long distances. These components include transceivers, transmitters, filters, poweramplifiers, multiplexers, antennas, and are used to take information in the form of data and modulate or demodulate that using a carrier wave in the radio frequency portion of the electromagnetic spectrum. RF components, products and sub-systems are vital to telecommunications and nearly all wireless communication applications including Space, Critical Communications and Defence.
