Electrical test methods Reflection coefficient and voltage standing wave ratio1 ScopeThis part of GB/T 11313 specifies the test method for the reflection coefficient, voltage standing wave ratio and return loss of the RF connector, including frequency. Domain method, time domain method, gated time domain method. 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 apply to each of multi-channel RF connectors and hybrid connectors RF channel testing.2 Normative referencesThe following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 11313.1 RF connectors - Part 1. General specification and test methods3 Terms and definitionsThe following terms and definitions as defined in GB/T 11313.1 apply to this document. 3.1 Reflection coefficient reflectionfactor The ratio of the magnitude of the reflected wave vector on any section of the connector to the magnitude of the incident wave vector is expressed by equation (1). Γ= Vr Vi= ZL-Z0 ZL Z0 (1) In the formula. Γ --- reflection coefficient; Vi --- incident voltage; Vr --- reflected voltage; Z0 --- the nominal impedance of the transmission line in ohms (Ω); ZL --- Transmission line termination load impedance in ohms (Ω). 3.2 Voltage standing wave ratio voltagestandingwaveratio The ratio of the maximum voltage to the minimum voltage on any section of the connector, its expression and the relationship with the reflection coefficient are expressed by equation (2). VSWR= Vmax Vmin = Vi Vr Vi-Vr = 1 Γ 1- Γ (2) In the formula. VSWR---voltage standing wave ratio; ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 11313.201-2018_English be delivered?Answer: Upon your order, we will start to translate GB/T 11313.201-2018_English as soon as possible, and keep you informed of the progress.
