The BALF-CC26-05D3 is an ultra-miniature balun manufactured by STMicroelectronics, designed for surface mount applications. It integrates a matching network and harmonics filter within a single component. The device operates within a frequency range of 2.4 GHz to 2.5 GHz, with a maximum frequency specification of 2.54 GHz. It provides a 50 Ohm impedance match between unbalanced and balanced ports. The insertion loss is specified at 1.35 dB. The component utilizes a flip-chip package configuration.
Verify the exact package type and pinout against the official STMicroelectronics datasheet before integration. Confirm that the customized matching impedance aligns with the specific requirements of the target CC26xx series device. Check for any last-time-buy notifications or end-of-life status associated with this component number to ensure long-term supply chain stability.
Select this component when designing circuits for Texas Instruments CC26xx series wireless microcontrollers requiring a compact solution. The integrated filter reduces board space compared to discrete components. Ensure the design supports the 50 Ohm system impedance. Consider the flip-chip mounting method for PCB layout constraints.
This balun belongs to STMicroelectronics' signal conditioning portfolio, specifically targeting low-power wireless applications. It serves as a passive RF component bridging the transceiver and antenna. The part is distinct from other baluns in the family due to its specific impedance matching tailored for CC26xx devices.
No public confirmed substitute part numbers are available in the provided documentation. Consult STMicroelectronics for direct replacements if this component is discontinued.
