Abstract:

The Radio Frequency Synchronising Unit (RFSU) is a module that is used in Radio Frequency Equipment. Reliability Prediction deals with an evaluation of design earlier to the actual construction of a system. In literature, Reliability Prediction is done by Macrocosmic Approach [11] by failure data collected from the field to estimate the parameters of the Failure Distribution. The MIL-217 [1] is used to establish and maintain standard methods for estimating the Fundamental Reliability by using Item ToolKit Software. However, this Macroscopic approach may be inappropriate and misleading when designing a new product or product with Advanced Technology [8]Hence, the Reliability prediction of Electronic Components used in Industrial Safety Systems require High Accuracy and Compatibility with the Working Environment. This can be overcome by predicting Reliability using Microcosmic Approach [12,13] to calculate reliability using SHERLOCK software based on failures, Failure Mechanisms, and Material properties to capture stress values. The SHERLOCK Software is developed based on the Physics of Failure (PoF) concept [7,10]. In this paper, the Macrocosmic approach using Item ToolKit Software and Microcosmic approach using Sherlock Software are compared in terms of Reliability. It is concluded that Microcosmic approach is using better than Macrocosmic approach.

I. Introduction

The RFSU plays a vital role in the communication systems of military, aerospace, and defence. The RFSU module synchronizes the Radio Frequency signals and transmits from the sending end to the receiving end. RFSU consists of three parts, they are calibration card, command & control unit, and Radiofrequency channel card. Generally, Radio waves are transmitted through an antenna then the Calibration card measures the receiver bandpass Radio Frequency signals and calibrates according to source data. Now, Command & control unit controls deviation in frequency signals with respect to exact values and maintains accuracy levels and it also maintains accuracy levels and sends to the radiofrequency channel card. It also maintains a balance in power consumption and environmental conditions. The Radio Frequency channel card is an important part of RFSU and can transmit signals to the receiving end with wireless communication. The RFSU module using in Military, Defence & Aerospace, and Industries. The RFSU module usually transmits and receives Radio Frequency Signals and also used for communication especially in Warzones. If it is failed, communication does not send from one end to another end, then it maybe one of the failure criteria in the armed force. So, in this scenario, RFSU module reliability analysis is more essential.
