Matching Transformers (50-to-75 ohms)

MT- 50/75 - 50 ohms to 75 ohms broadband impedance transformer

MT-50/75 is designed to impedance match a 75ohm device, such as RF filter or amplifier, to a 50ohm system. This prevents mismatch and signal reflection. It is a cost-efficient solution to convert a 75ohm signal for a 50ohm measurement, or vice versa, for measurement or transformation purposes. It does this with good return loss to improve measurement accuracy. A further advantage of this this matching transformer is that it features a low through loss, preserving much more of your input signal than a matching pad (6 dB) would.
Model MT-50/75-FM is optimized for FM band operation: >30 dB return loss, 20 watts (see pdf)

    Channel combiners are bandpass filter networks, consisting of individual bandpass filters joined together at one common port. Available for combining or separating up to 7 non-adjacent channels in one enclosure. Multiple units are used to combine large number of channels (e.g., 36 chs Headend).

    • Available for VHF, UHF, and CATV channels
    • Custom channel combining available
    • Non-Adjacent bandpass for each channel removes spurious signals
    • Passband loss: 2dB VHF, 3 dB UHF typical

    Isolation between channels:

    • VHF/CATV (5-300 MHz) > 25dB ±8 MHz
    • VHF/CATV (300-450 MHz) > 20dB ±12 MHz
    • CATV/UHF (455-600 MHz) > 20dB ±18 MHz
    • UHF (600-860 MHz) > 20dB ±20 MHz

    Channel combining in one enclosure:

    • VHF/CATV (5 to 400 MHz) requires > 8 MHz frequency separation
    • CATV(400 to 560 MHz) requires > 12 MHz frequency separation
    • UHF/CATV (560 to 800 MHz) requires > 18 MHz frequency separation.
