This device is an ultra-miniature balun. The BALF-SPI2-01D3 integrates matching network and harmonics filter. Matching impedance has been customized for the ST S2-LP transceiver. The BALF-SPI2-01D3 uses STMicroelectronics IPD technology on non-conductive glass substrate which optimize RF performance.
Key Features
- 50 Ω nominal input / conjugate matched to ST S2-LP for 860 - 930 MHz frequency operation
- Low insertion loss
- Low amplitude imbalance
- Low phase imbalance
- Small footprint
- Very low profile < 620 μm after reflow
- High RF performance
- RF BOM and area reduction
- ECOPACK®2 compliant component
