4.3-10 Connectors - Application and Performance Overview

Choosing between classic interfaces such as 7/16, N or 4.1/9.5 connectors and the new interface 4.3-10 can have a significant impact on how a particular network will perform. There are several important considerations to make when choosing a connector, including the network design and the choice of the Mobile Telecommunications System used. This paper will compare and contrast these two categories of connectors (classical and new), highlighting their differences in terms of electrical and mechanical performance in particular applications.

Because Long Term Evolution (LTE) networks feature an increased mobile data rate of 100 Mb/s, this higher transmission rate will expose PIM (Passive Intermodulation) vulnerabilities in today’s networks with frequency division duplexing. Fourth generation networks require superior network transmission fidelity, much higher than previous generations. Network operators also face the challenge of maintaining customer loyalty in an unforgiving competitive arena. As such, good network PIM performance and PIM testing are now imperative. One of the major benefits of the new 4.3-10 interface is its reliability in terms of PIM.

The size of a particular connector has a major impact in today demanding applications. Mast or roof installations require much lighter products and therefore we see a trend towards miniaturization of RRHs (Remote Radio Heads). Additionally the space available for RF ports is shrinking, and Mimo antenna systems require more antenna lines. Furthermore; reduced footprint and a higher number of ports requires connectors which can be positioned closer together without the need for tools such as torque wrenches.
