Abstract
This paper is a study regarding the Radio Frequency (RF) connector characteristic (insertion loss) in applications at 50 Ω Impedance from 45MHz until 50GHz by using the Network Analyzer and two type of calibration kits that are Electronic Cal (E-Cal) Module and Mechanical Calibration (M-Cal) Kits. RF connector will always assume as idle (lossless) in a calibration system. It can exist in varying types in dimension and length (delay line). The purpose of this study is to determine the significant and impact of the RF connector loss against its frequency range. The objective is to gain more knowledge about the RF connector characteristic, network analyzer and the two type of calibrations kits setting and usage. One port and full two ports calibration techniques are used to determine the loss of RF connector. This study will analyze the differences between both techniques (one port and full two-port calibration) and calibration kits (E-Cal and M-Cal kits) in the RF connector insertion loss.
Highlights
Radio frequency (RF) connectors are found in a broad range of electronic equipment for extending the dynamic range of measuring equipment
RF connector can be found in any dimension and frequency range
The accuracy of the calibration standard in the network analyzer and the calibration method either one port or full two-port calibration was used in conjunction with the error correction model by using an automated Electronic Cal (E-Cal) Kit [4]
Summary
Radio frequency (RF) connectors are found in a broad range of electronic equipment for extending the dynamic range of measuring equipment. RF connector can be found in any dimension and frequency range. The objective of this work is to create a new process to characterize RF connector using a network analyzer [1]. It is to determine the insertion loss and port match of the RF connector. This covers the calibrations kit usage on the network analyzer. Precision Slotless Connector (PSC) is of higher quality than the Precision Variety (Slotted) and can make a better repeatable measurement [3]. A PSC is defined as a metrology grade connector It is expensive, reliable, repeatable and precision in dimension. They are stuck in a particular location on the RF path and are called Voltage Standing Wave Ratio (VSWR)
