As broadcast television became a reality in the 1950s the BNC connector was the selected interconnect. It was a low frequency, 50Ω connector used in the 50-100 MHz range. As the industry progressed, and with the improved quality of broadcast and the advent of color, this BNC connector proved to be no longer adequate for the job. A 75Ω connector was designed to match the impedance of the 75Ω cable used in broadcast industry. This was a serial digital (SD) connector that eventually would work well at frequencies up to 1GHz. To meet this demand, Winchester Interconnect developed the SBC series. The next innovation was high definition broadcast which uses a high bandwidth in the frequency range of 2.3 GHz - 4.5 GHz. Winchester Interconnect’s HBC series has been designed to meet this demand.
