Broadband Video Balun

 Video Balun. Broadband video (CATV) over UTP, once thought to be impractical (or impossible) is now commonplace, due to the use of the PV880 Series of Broadband Video Baluns from ETS. Commercial and professional grade video can be transmitted over Category 5 and better UTP.Get more news about Broadband Balun,you can vist our website!

Distance is a function of frequency and signal level. Using Category 5 or better cable, all channels up to 26, at a drive level of not more than 36dBmV will accommodate 100 meters. The usable distance is reduced at higher channels, reaching 50 meters at channel 78.

Application Note Off air channel 26 is 542 to 548 MHz. CATV allows packing channels into unused on-air frequencies.The effective output balancing capability of this balun is proven by the close agreement between the measured and simulated results. Diode detectors are nonlinear devices used for extraction of DC from free space transmission, achieving RF to DC conversion. Detectors are of popular use today in RF-ID tags, virtual batteries, power scavenging, and many other portable applications. The dominating factor on the performance for this device is responsivity (mV/mW), which depends on the input matching, and in the relation of power level to input impedance. Here, an accurate comparison between model measured detectors has been accomplished, and a sensitivity study has been applied to the input impedance to represent variations in responsivity due to input mismatch.At last an End-Loaded Planar Open-Sleeve Dipole (ELPOSD) is realized resulting on a printed dipole structure offering broadband response.
