transformer balun
Datasheet − production data
Description
STMicroelectronics BAL-CC25-02D3 is an ultra
miniature balun which integrates a matching
network in a monolithic glass substrate. This has
been customized for the CC2541 RF
transceivers.
It’s a design using STMicroelectronics IPD
(integrated passive device) technology on non-
conductive glass substrate to optimize RF
performance.
