50 Ω ultra thin balun with integrated harmonic filter

This device is an ultra-miniature extra thin balun that integrates matching network and harmonics filter.

Matching impedance has been customized for the nRF51822-CTAA and CTAC WLCSP Nordic Semiconductor circuits.

Based on IPD technology on high resistivity silicium it optimizes the RF performance.

The BALF-NRF01J5 has been tested and approved by Nordic Semiconductor.

Key Features

  • 50 Ω nominal input / conjugate match to Nordic Semiconductor chips nRF51822 WLCSP
  • Low insertion loss
  • Low amplitude imbalance
  • Low phase imbalance
  • Small footprint: < 1.2 mm2
