Description
STMicroelectronics' BALF-112X-01D3 is an ultra-
miniature balun, integrating both matching
network and harmonics filter.
Matching impedance has been customized for
the CC1120, CC1125, CC1175 and CC1200
transceivers from Texas Instruments.
The device uses STMicroelectronics' IPD
technology on a non-conductive glass substrate,
which optimizes RF performance.
