BALF-CC26-05D3 50 nominal input / conjugate match balun CC2610, CC2620, CC2630, CC2640, CC2650 MHz, with integrated harmonic filter Datasheet - production data Description STMicroelectronics BALF-CC26-05D3 is an ultra-miniature balun, integrating both matching network and harmonics filter. Matching impedance has been customized for the TI CC26xx series 5x5 SimpleLink multistandard wireless MCU. The device uses STMicroelectronics IPD technology on a non-conductive glass substrate, which optimizes RF performance. Figure 1: Pin configuration Features 2.45 GHz balun with integrated matching network Matching optimized for CC26 series 55 external differential Low insertion loss Low amplitude imbalance Low phase imbalance Coated Flip-Chip on glass Small footprint < 1.5 mm Benefits Figure 2: Block diagram Very low profile High RF performance PCB space saving versus discrete solution RF BOM and size reduction Antenna (50 ) Efficient manufacturability Not necessary if internal bias is used Pin 3/4 RX/TX Pin 2 RFN Pin 1 RFP BALF-CC26-05 July 2016 DocID029603 Rev 1 1/8 www.st.com This is information on a product in full production.
