Datasheet - production data
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
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.
