Connectors play a decisive role in the good performance in transmission of RF signals between base stations or remote radio heads and antennas. In the future, mobile networks will require RF signal transmission to be implemented with tighter and tighter space constraints, less losses and the lowest interferences with regard to passive intermodulation. These market requirements led in the last few years to the introduction of the 4.3-10, of which Telegärtner was one of the co-developers.
The 2.2-5 series has taken the successful concept of the 4.3-10 and turned it into a smaller design. Whilst the 4.3-10 typically requires the same space as a classic N connector, the 2.2-5 only has the standard space requirements of the TNC series. Despite the clear reduction in size and weight, the 2.2-5 series possesses comparable electrical and thermo-climatic properties to the 4.3-10 series and can be used with cables up to ½” corrugated cable both indoors and outdoors.
The 2.2-5 series enables a robust and PIM stable design in the smallest space. The space requirements for a typical 4 hole flange jack are only 17.4 x 17.4 mm. This is the same as the usual mounting surface for the TNC series.
Therefore the 2.2-5 requires around 53 % less space than the 4.3-10 series and 70 % less space than the 7-16 series. Hand in hand with the size and material reduction, there is also a cost and weight reduction, meaning this series is ideal for small cell applications. Despite the small size, relatively thick and therefore low loss cables up to ½” can be used.
