CAT-5 Video Receivers
Analog Devices high speed, differential CAT-5 video receivers and equalizers compensate for the transmission losses of UTP and coaxial cables up to 300 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry controls the gain functions of the individual stages so that the lowest noise can be achieved at short-to-medium cable lengths. Our video receivers provide excellent common-mode rejection that enables the use of low cost, unshielded twisted pair cables in noisy environments.

RF Architectural Shielding Products
EMI (Electromagnetic Interference) is often used interchangeably with RFI (Radio Frequency Interference). However, EMI can be any frequency of electromagnetic noise, whereas RFI is a relatively narrow range of electromagnetic noise on the EM spectrum. EMI Shielding can be used to mitigate electric and magnetic radiation across various spaces. Radio Frequency (RF) Shielding can be used to mitigate RFI with specifically designed enclosures that can block RFI. As well, RF Shielding can include application of RF Shielding paints, fabrics, and other materials.
