On-wafer power measurements of BAW filters non-linearities

Abstract

In the wireless communications systems, one of the main parameters should be known for every component is the limit of its linear zone. The linearity or non-linearity of filters contributes to the ones of systems and have to be characterized. This paper describes on-wafer power measurements and its use to determine output power at 1dB compression and IMD of BAW filters for radiocommunications wireless applications around 2.0GHz.
