BALF-112X-01D3

BALF-112X-01D3 50 ohm nominal input / conjugate match balun CC1120, CC1125 (868-928 MHz), with integrated harmonic filter Datasheet - production data Flip-Chip (8 bumps) package 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. Features  50 Ω nominal input / conjugate match to CC1120, CC1125  Low insertion loss  Low amplitude imbalance  Low phase imbalance  Small footprint Benefits  Very low profile (< 670 μm thickness)  High RF performance  RF BOM and size reduction Applications  868 MHz and 928 MHz impedance-matched balun filter optimized for Texas Instruments® CC1120, CC1125, CC1175, CC1200 sub-GHz RFICs.
