BALFLB-WL-09D3 - ultra-miniature balun

General Description

STMicroelectronics BALFLB-WL-09D3 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.

Key Features

  • QFN STM32WL sub-GHz wireless microcontrollers impedance matched balun and Tx harmonics filter.
  • Optimized for QFN STM32WL sub-GHz wireless microcontrollers in high power mode and dedicated to 2-layers PCB.
  • 50 Ω nominal input / conjugate matched balun to QFN 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.
