Omfang

IEC 63138-4:2025, which is a Sectional Specification (SS), provides information and rules for the preparation of Detail Specifications (DS) for type L32-4 and L32-5 circular connectors with four RF channels and five RF channels, as well as a detailed specification of the blank format. The L32-4 and L32-5 circular connectors with 50 Ω nominal impedance has four RF channels and five RF channels which can be engaged and disengaged at the same time. They are characterized by threaded coupling mechanisms, anti-misinsertion mechanism, and the operating frequency of each channel is up to 4 GHz. These connectors have been widely used in mobile communication system like TD-SCDMA and TD-LTE and can also be used in some similar equipment. This document also specifies mating face dimensions for general connectors (grade 2), gauging information and tests selected from IEC 63138-1, applicable to all Detail Specifications relating to type L32 4 and L32-5 circular connectors. This document cancels and replaces IEC 61169-59:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61169-59:2017: a) use of IEC 63138-1:2019 as its generic specification instead of using IEC 61169-1:2013; b) all the subclauses and test methods are in line with IEC 63138-1:2019; c) dimension "g" in Table 3, Table 4, Table 7 and Table 8 has been changed from "0,00 min. to 0,8 max." to "1,6 min. to 2,1 max.".
