BALF-NRG-02J5 Enhanced Balun for BlueNRG
STMicroelectronics' BALF-NRG-02J5 50 Ω ultra-thin balun with integrated harmonic filter/conjugate match balun to ST BlueNRG-134
STMicroelectronics' ultraminiature BALF-NRG-02J5 balun integrates both matching network and harmonics filter. Matching impedance is customized for both the BlueNRG-1 and the BlueNRG-2 Bluetooth® Low Energy (BLE) systems-on-chip. As a single-component solution, it simplifies RF complexity and provides optimized link budget in a footprint less than 1.2 mm² in extra low profile.
Features
- Small footprint
- RF BOM reduction
- Extra low profile <350 µm after reflow
- Simplify matching and filtering network complexity
- Low-temperature variation compared with discretes
- Monolithic RF solution for matching, balun, and harmonic filter
- Optimum impedance matched to ST BLUENRG-1 and BLUENRG-2
- PCB space reduction from 72 mm² using discretes down to 1.2 mm² with balun
Applications
- Medical
- E-metering
- E-payment
- Asset tracking
- Tags and finders
- Toys and gaming
- Wearable devices
- Smart home and smart cards
