Abstract

Typical early failures and reliability of modern cordless mobile portable devices, characterized by their inability to provide quality RF performance, are analyzed. Multifaceted specifics of device technology, reliability and FA are discussed. Systematic analytical methodology is applied and RF-specific methods are outlined. Product and application statistics are displayed. Integrated block diagrams and joint FTA-FMECA are developed. FA results and classification of typical full, parametric, unbalanced and intermittent fault-failure modes and mechanisms for characteristic components and circuitries are presented. Fault evolution and interactions altering failure criticality are exemplified and substantiated. Reduction of early failures leads to significant reliability improvement, design and manufacturing cost reduction. RF reliability theoretical interpretation and modeling are discussed
