BALF-112X-01D3 50 ohm nominal input / conjugate match balun CC1120, CC1125 (868-928 MHz), with integrated harmonic filter Datasheet - production data 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.
