2000-03-30 RF measurements on SIEGET bipolar transistors: Predicting performance straight from the wafer
Multistage measurements are intended to ensure unrestricted operation of RF transistors. Recently, RF properties could only be measured on packaged components, while DC measurements alone cannot provide reliable indication of RF performance. Not until on-wafer testing emerged did it become possible to evaluate the RF parameters of production batches right from the wafer fabrication stage. This application note cites the example of on-wafer RF testing of SIEGET transistors.
