Signal tappers, also known as signal samplers, operate similarly to directional couplers but without the directivity.
Signal tappers are a low cost, high power, broad band solution for Distributed Antenna Systems (DAS). Tappers offer very accurate coupling value and operate on a wider bandwidth than directional couplers.
The Microlab DN-x4FN series of tappers split high power cellular signals in fixed ratios from 1000:1 to 2:1 with minimal reflections or loss. They operate over a very broad range of wireless bands from 350 MHz to 5,850 MHz (there is no coupling 1550 to 1650 MHz).
The lightweight design allows easy attachment to a wall using the supplied bracket.
Microlab antennas and passive components both carry a guarantee for low PIM which improves coverage and capacity thereby optimizing network performance. PIM, or passive intermodulation, is form of distortion that occurs in devices like antennas as a result of nonlinearities in the system. It can be caused by dissimilar materials, design flaws, or corrosion by weather or age. PIM can cause significant disruption to system performance. The DN-x4FN series is designed with only a few solder joints and an air dielectric, so loss is minimized and reliability enhanced.
