LOW LOSS IMPEDANCE TRANSFORMERS IMPLEMENTED AS INTEGRATED PASSIVE DEVICES AND RELATED METHODS THEREOF

摘要

Disclosed are apparatus and methods related to low loss impedance transformers implemented as integrated passive devices (IPDs). In some embodiments, an IPD can include an autotransformer implemented within a body. The autotransformer can include primary and secondary metal traces implemented in respective planes separated by a distance. The autotransformer can be configured to, for example, facilitate impedance matching of radio-frequency (RF) signals. In some embodiments, the IPD can include a surface that allows mounting of one or more components thereon to provide space savings in RF modules. Examples of fabrication methods as well as products that can benefit from such IPDs are disclosed.
