Microlab Signal Tappers, also known as Signal Sampler, are very similar to directional couplers. The signal sampler extracts all signals regardless of the direction of flow. These include direct-coupled resistive samplers as well as electrostatic and electromagnetic probe samplers. Tappers are frequently used in Distributed Antenna Systems (DAS) and are available with either N or 7-16 mm DIN connectors.
Distributed Antenna Systems (DAS) are a big part of the wireless infrastructure growth. With the increase of the system architecture, there are more frequency expansion challenges in DAS. In order to cover these frequency extremes in a single system, economic factors compromise the performance. The performance trade-off during the design stages is the biggest challenge in DAS applications. Usually unequal splitters and directional couplers used to divide or combine wireless signals. In practice, the smaller more conveniently sized directional coupler is usually selected.
