      Product Description


      UBS designs and manufactures a line of 1-5/8” EIA, rotating flange, directional couplers for accurate power measurements in rigid and coaxial air-line transmission systems. The loop coupler series includes models which cover entire frequency ranges from 450 to 1000 MHz (UHF-Band) and 1000 to 3000 MHz (L/S-Band), as well as models which have been optimized for narrower bandwidths (i.e DTV channel). The couplers are ideally suited for DTV and wireless applications by virtue of their high power capability, low insertion loss, high directivity and excellent matching with the prime line. The loop couplers are available in a single, dual, triple and quadruple probe configuration for sampling incident and/or reflected power. Coupling values (see Electrical Specification) must be specified for each independent coupling port.
