STMicroelectronics BALFLB-WL-07D3 is an ultra-miniature balun. This device integrates a matching network, balun, and harmonics filter. Matching impedance has been customized for the STM32WL sub-GHz wireless microcontrollers.

It is using STMicroelectronics IPD technology on a nonconductive glass substrate, which optimizes RF performances.

Key features
  • BGA STM32WL sub-GHz wireless microcontrollers impedance matched balun and Tx harmonics filter
  • Optimized for BGA STM32WL sub-GHz wireless microcontrollers in high power mode and dedicated to 4-layers PCB
  • 50 Ω nominal input / conjugate matched balun to BGA STM32WL
  • 50 Ω nominal impedance on antenna side Tx and Rx
  • Deep Tx rejection harmonic filter
  • Low insertion loss
  • Small footprint
  • Low profile ≤ 630 μm after reflow
  • High RF performance
  • RF BOM and area reduction
  • ECOPACK2 compliant component
