多通道射频连接器 第2部分：MQ4系列圆形连接器分规范

[中文适用范围]： 本部分 IEC 63138 是一个分规范（SS），提供了用于制备具有四个 RF 通道的 MQ4 系列圆形连接器的详细规范（DS）的信息和规则，以及空白格式的详细规范。 MQ4 系列圆形连接器具有 50 Ω 标称阻抗，具有四个可以同时接合和分离的 RF 通道。插头连接器有两种版本，一种是快速锁定版本，另一种是螺纹版本。插座连接器提供两种耦合机制，快速锁定和螺纹耦合。 MQ4 系列圆形连接器可用于移动通信系统和其他通信设备。 本文件还规定了 MQ4 系列圆形连接器的配合面尺寸和测量信息，以及从 IEC 63138-1 中选择的测试，适用于与 MQ4 系列圆形连接器相关的所有详细规范。 [外文原描述]： IEC 63138-2:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 63138-2:2023, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for MQ4 series circular connectors with four RF channels, as well as a detailed specification of the blank format. An MQ4 series circular connector with 50 Ω nominal impedance has four RF channels which can be engaged and disengaged at the same time. There are two versions of plug connectors, one is a quick-lock version, and the other is a threaded version. The socket connector provides two coupling mechanisms, a quick-lock and a threaded coupling. MQ4 series circular connectors can be used in mobile communication systems and in other communication equipment. This document also specifies the mating face dimensions and gauging information of MQ4 series circular connectors, and tests selected from IEC 63138-1, applicable to all detail specifications relating to MQ4 series circular connectors.
