Continuing improvements in hybrid technology have resulted in the extension of upper frequency limits into the microwave spectrum. Now, microwave assemblies based on thin or thick film technology are relatively common, offering a wide choice of system fabrication methods which are truly solid state and compatible with modern active devices.

Recently, considerable interest has arisen in the use of thick film technology for microwave circuit applications. The thick film process can be used to fabricate microwave circuits that perform just as well as thin film counterparts in the lower-frequency region below 1 GHz, but systematic efforts
After a short historical introduction, the basic data about the content, crosssection and morphology of thick film glaze resistors (TFRs) is given. The second part of the paper presents a review of the known conductive mechanisms in TFRs and resisitivity dependence on conductive phase content. The c
