• Torque Recommendations for Optimum PIM

    One of the most critical parameters in today's congested wireless networks is Passive InterModulation or as it is commonly known, PIM. Not only is it necessary to select properly designed and tested low PIM components, but they must also be connected to the interconnecting coaxial cable with the appropriate torque.

  • Choosing the Best Power Divider

    As systems become more and more complex, choosing how best to combine two or more RF signals has become a far more difficult question to answer, and this application article is intended to highlight the benefits of the many options available to today's system engineer.

  • Couplers & Samplers Explained

    Couplers and samplers are similar to power dividers in that they each divide an RF signal into two or more signals. However, power divider outputs are of roughly equal amplitudes; couplers and samplers have a main line with one or more auxiliary lines.

  • Directional Couplers As Signal Combiners

    Combining different wireless carriers does not always mean using complex filters or acceptance of the 3 dB loss of hybrid combiners. The choice usually starts with considerations of the guard band between the signals and the acceptable limitations of passive intermodulation (PIM).

  • Dividers & Combiners

    A wide and often confusing assortment of power dividing and combining methods are available to the system designer, each of which has its own attributes and deficiencies. In addition, the same component can often be used to both divide and combine. This application note is intended to guide the system designer in the selection of the optimum component for any particular need.

  • Reactive vs Wilkinson Splitters

    Splitters are used extensively in wireless signal distribution networks, to split the base station transmitted signal, Tx, into many different paths to reach multiple antennas, and at the same time to transmit the signals received by the antennas, Rx, back to the base station receiver.
