Abstract :
Due to the complex nature of electronically steerable phased arrays, higher operating frequencies, increased density requirements, and wider operating temperatures, there has been increased focus on technology development with thinner microwave laminate substrates to create a multi-layer boards that are phase stable with temperature and compatible with embedded resistors utilized for Wilkinson Power Dividers. These laminates can range from 0.003" to 0.010" in thickness with frequencies well into the Ka Band. This paper explores technical advances and technical considerations placed on these materials as they are required for these advanced systems. This paper also discusses the processing limitations placed on existing materials and technical developments to overcome these deficiencies.
