Accurate balun covering DC up to 300 MHz in one measurement

This high precision convertor allows to use a standard 50 Ohm spectrum or network analyzer to measure all physical layer parameters of a balanced 100 Ohm network (wireline, pair, cable or component) with an unmatched accuracy over the entire range from DC up to 300 MHz (with 500 MHz reach). This overcomes the limitation of common classic baluns in terms of frequency response and frequency bandwidth that are designed to be accurate for only a part of that spectrum. Moreover, most baluns introduce reflections that affect impedance measurements while such reflections are not present in reality. Accurate and representative measurement results in higher frequency band have become necessary for the Broadband Industry as of new transmission technologies like G.fast working in frequency range of 106 and 212 MHz enabling 2 Gbps over copper networks. The BIMA 300A is as well as a balun, a measurement reference and an impedance bridge perfectly suitable to measure all physical layer parameters (ABCD) like insertion loss, delay and impedance in a correct and repeatable way. BIMA 300A can be used with any type of Network or Spectrum Analyzer. It is the preferred choice of the analog expert who is after correct and accurate physical layer measurements in any part of targeted frequency spectrum - starting from a reference level of 0 dBm at all ports.
