ANSI SCTE 200-2016 pdf free download.Specification for a 75 ohm ‘MMCX’ Connector (MMCX-75), Male & Female Interface
1. Scope
The purpose of this document is to specify requirements for the male/female interface of a 75 ohm, 3 GHz rated connector series generically known as MMCX-75. This is an indoor connector with applications in controlled environments such as headends and hubsites where high density platform chassis are used. MMCX-75 connectors are not intended to be mated with 50 ohm MMCX design counterparts. All requirements of this document are measured after installation per manufacturer’s instructions of the cable into the connector. This document will address only the interface, not the connector body, the cable requirements, and the connector attachment to the cable or PC board. Mechanical, electrical and environmental performance is defined to ensure a reliable connection for permanent installations, as well as temporary adapters and calibration standards.

4. Compliance Notation
shall This word or the adjective “required” means that the item is an absolute requirement of this specification. shall not This phrase means that the item is an absolute prohibition of this specification. forbidden This word means the value specified shall never be used. should This word or the adjective “recommended” means that there may exist valid reasons in particular circumstances to ignore this item, but the full implications should be understood and the case carefully weighted before choosing a different course. should not This phrase means that there may exist valid reasons in particular circumstances when the listed behavior is acceptable or even useful, but the full implications should be understood and the case carefully weighed before implementing any behavior described with this label. may This word or the adjective “optional” means that this item is truly optional. One vendor may choose to include the item because a particular marketplace requires it or because it enhances the product, for example; another vendor may omit the same item. deprecated Use is permissible for legacy purposes only. Deprecated features may be removed from future versions of the standard. Implementations should avoid use of deprecated features.
7.3.1. Insertion and Retention
Force Depending on whether the MMCX-75 interface connections are to be used individually or in conjunction with a multi-connector header, the required interface insertion and retention forces can vary. The data in this specification is for individual connector mating forces. Manufacturer specifications for the female socket insertion and retention forces should meet equipment requirements when tested as follows
