Product catalog summary

Introduction
The document discusses the importance of selecting the appropriate connector for network performance, comparing classic interfaces like 7/16, N, and 4.1/9.5 with the newer 4.3-10 interface. It highlights the impact of connector choice on network design, particularly in LTE networks where PIM (Passive Intermodulation) performance is critical.

Historical Interfaces
The N connector, developed in the 1940s, is a medium-size RF connector. The 7/16 interface, from the 1960s, is used in cellular networks and requires high torque for stable PIM performance. The 4.1-9.5 connector, designed in the 1970s, offers a balance between robustness and space efficiency. All these interfaces depend heavily on torque for electrical performance.

Evolution of 4.3-10
The 4.3-10 connector, developed by HUBER+SUHNER, addresses the need for compact, high-performance connectors in mobile networks. It is lighter and smaller, fitting within a 1-inch flange, and offers superior PIM performance without the need for high torque.

Features and Benefits of the 4.3-10
This connector separates the electrical and mechanical planes, allowing for lower force requirements and eliminating the need for high torque. It supports screw, hand-screw, and push-pull mechanisms, all providing consistent PIM and return loss performance. The design is robust, with protected contact surfaces, making it suitable for field use.

Performance Characteristics Comparison
The document includes a table comparing the 4.3-10 with other connectors in terms of frequency range, PIM, return loss, RF leakage, and mechanical data. The 4.3-10 offers superior performance with lower torque requirements and greater flexibility in installation.

Applications
The 4.3-10 is ideal for new base stations, distributed antenna systems (DAS), in-building architecture, and small cell applications. It is particularly suited for environments with space constraints and high electrical performance demands.

Conclusion
With increasing wireless data usage, network infrastructure must provide adequate coverage and bandwidth. The 4.3-10 connector meets modern requirements for compactness, robustness, and reliable electrical performance, offering significant advantages in communication systems.

WHITE PAPER 4.3-10: choosing the right connector Introduction Choosing between classic interfaces such as 7/16, N or 4.1/9.5 connectors and the new interface 4.310 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....

WHITE PAPER 4.3-10: choosing the right connector Historical Interfaces The N connector (in full, Type N connector) is a threaded, weatherproof, medium-size RF connector. It was invented in the 1940s and was one of the first connectors capable of carrying microwave-frequency signals. The 7/16 interface was developed in the 60’s and is used in cellular networks and base stations as well as in other communications equipment. At that time large corrugated cables and high transmitted power were a challenge for the N type interface. Historically the 7/16 interface had a slotted outer contact. Then...

WHITE PAPER 4.3-10: choosing the right connector The decoupling of the electrical and mechanical plane gives the possibility of realizing the connection with a lower coupling torque. There is no longer the need for a high torque value to reach high electrical performances. On the contrary, this design even facilitates a hand-screw solution or a push pull design due to its innovative design. The coupling mechanism is no longer influencing PIM or return Loss performances and all of the 3 configurations (screw, hand-screw or push pull connectors) are performing in the same way. For better handling...

WHITE PAPER 4.3-10: choosing the right connector Applications The 4.3-10 is the ideal choice for applications in new base stations as well as for solutions for distributed antenna systems (DAS), in-building architecture and in small cells applications. In base stations the 4.3-10 can be used for interconnections both in the remote radio head as well as for the interface on the antenna and on the jumpers. In multi-operator, multiband DAS where RF signals have to be combined, terminated, or distributed to the antenna. In small cells applications, the 4.3-10 is particularly suited for the challenging...
