1 Scope

GB/T 11313.202-2018 is the Chinese national standard on radio-frequency connectors - part 202: electrical test methods - insertion loss, in the field of telecommunications and audio-video engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 17 September 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 January 2019. Classification: ICS 33.120.10, CCS L27. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This part of GB/T 11313 specifies the test method for insertion loss of RF connectors. This section applies to the RF connector of the cable (hereinafter referred to as the cable connector) and the microstrip RF connector (hereinafter referred to as the microstrip connection). And RF connector adapters (hereinafter referred to as adapters), etc., also applicable to multi-channel RF coaxial connectors and hybrid connectors RF channel testing.

3 Terms and definitions

The following terms and definitions as defined in GB/T 11313.1 apply to this document.

3.1 Insertion loss insertionloss The power loss generated when the device under test is connected to the transmission system. The insertion loss of the RF connector is expressed by equation (1). IL=-10lg P2 P1 ÷ (1) In the formula. IL

--- insertion loss in decibels (dB); P1

--- the input power of the signal source to the RF connector, in watts (W); P2

--- The output power that the signal source transmits to the load through the RF connector, in watts (W).
