ST Microelectronics – BALF-NRG-02D3
The BALF-NRG-02D3 ultraminiature balun integrates both matching network and harmonics filter. Matching impedance is customized for both the BlueNRG-1 and the new-generation BlueNRG-2 Bluetooth® Low Energy (BLE) systems-on-chip. As a single-component solution, it simplifies RF complexity, provides optimized link budget in a footprint less than 1.2 mm². Its non-conductive glass substrate offers low dispersion over temperature, surpassing current solutions.
Key Features
- 50 Ω nominal input / conjugate match to BlueNRG device
- Low insertion loss
- Low amplitude imbalance
- Low phase imbalance
