Description
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.
