Telecommunications

Telecommunications Equipment - RF and Microwave Products and Components - Materials used in the telecommunications industry are selected based on various criteria such as signal isolation and insulation, frequency capability, electromagnetic properties. Thermal interface materials may be required to exchange or dissipate heat and some units may require electro-magnetic interference (EMI) shielding. Certain materials are also used to meet flame rating specifications, especially UL 94V-0.

Applications: Connectors, Terminations, Antennas, Amplifiers, Switches, Attenuators, Power Dividers, Signal Processors

The radio spectrum of the electromagnetic scale runs from ULF (Ultra Low Frequency) up the EHF (Extremely High Frequency). The higher end of this range is known as the Microwave Range which runs 100 MHz up to 100 GHz. The start of the microwave range begins with ISM bands from 315 to to 915 MHz, and continues to ISM bands up to the 2.4 GHz ISM band. Next is the UWB range which runs from 3.1 to 10.6 GHz. Frequencies above this range are considered EHF which pushes beyond the microwave range and into 4G cellular bands from 56 GHz to 100 GHz.
