NEW RF-Interface for Mobile Communications Connector Series 4.3-10 New Interface 4.3-10 Copyright © Rosenberger 2013 V1.0 www.rosenberger.com | 2 New Interface Standard 4.3-10 Three global Telecom OEMs Copyright © Rosenberger 2013 V1.0 Created by an international consortium of competent connector manufacturers and three global telecom OEMs Aiming towards a solution for future markets needs. Proposal for IEC filing www.rosenberger.com | 3 Design of 4.3-10 Interface Versatile solution with one universal jack and 3 different plug types Quick installation for all needs with guaranteed low PIM values Future proof due to smallest form factor Copyright © Rosenberger 2013 V1.0 www.rosenberger.com | 4 Features of 4.3-10 Interface Reliable PIM independent of torque -> the 4.3-10 connector system allows constant PIM values for a wide range of torque values. Therefore limits most installation failures for the future. Excellent electrical performances Low and reliable PIM (even if the connector is not fixed finally during installation, the PIM-Performance is excellent – independent of torque) Small form factor – future proof for 8x8 MiMo-applications Very good RL/IL performance High screening efficiency High power performance for its form factor Lower torque values Copyright © Rosenberger 2013 V1.0 5x less torque needed Longer life time guarantee www.rosenberger.com | 5 Benefits of 4.3-10 Interface Smallest footprint 40% less than 7-16 Light weight modules Due to low weight components Flexibility for different applications Due to the 3 different plug types Guaranteed Low PIM independent of torque Copyright © Rosenberger 2013 V1.0 www.rosenberger.com | 6 Torque independent low and reliable PIM Intermodulation UMTS II 2600 MHz while climatic stress acc. to IEC 62037-3, sweep mode, 2 x 20 Watt DUT Rosenberger cable assemblies hand screw cold_1 cold_2 heat_1 heat_2 Limit -80 Intermodulation [dBm] -90 -100 -110 -120 -130 -140 2545 2550 2555 2560 2565 2570 2575 2580 Frequency [MHz] Intermodulation UMTS II 2600 MHz while climatic stress acc. to IEC 62037-3, sweep mode, 2 x 40 Watt DUT Rosenberger cable assemblies push pull cold_1 cold_2 heat_1 heat_2 Limit -80 low and reliable PIM independent of torque Intermodulation [dBm] -90 -100 -110 -120 -130 Web-Link PIM measurement: -140 2545 http://www.youtube.com/watch?v=yJKDia4Vvqc&feature=youtu.be Copyright © Rosenberger 2013 V1.0 2550 2555 2560 2565 2570 2575 2580 Frequency [MHz] www.rosenberger.com | 7 Comparison: 4.3-10 vs. DIN 7-16 / MiniDin 4.1-9.5 connectors 4.3-10 4.1-9.5 (Mini DIN) 7-16 (DIN) 25.4 mm 25.4 mm 32 mm > 5 Nm > 10 Nm > 25 Nm Until stop by hand n.a. n.a.

For 4.3-10 these planes have been separated, which also results in a lower coupling torque (Figure 1). This results in higher reliability, because the 7-16 design only have a good performance if the connectors have been screwed together with the correct torque. Also the sealing situation is only ensured at 7-16 if the correct torque is used during connecting. In the 4.3-10 design the electrical performance is maintained even if the interface is not completely tightened. This offers the possibility to have a hand-screw and quick-lock cable connector with high reliability – independent of torque. With the 4.3-10 interface, easy handling and reliable useage by the installation companies is possible.
