Detailed Description for BALF-SPI-02D3
Product Overview
BALF-SPI-02D3 integrates the balanced/unbalanced transformation required in 433 MHz band signal paths. Its network is customized for ST SPIRIT1, presenting the stated 50 Ω antenna-side input / conjugate match relationship while reducing the number of external RF matching components. Only confirmed frequency, matching, package and application data is included; unavailable numerical limits are omitted.
The device is customized for ST SPIRIT1; its complex differential match is therefore part of the ordering code rather than a generic transformer ratio. The specified RFIC, package option and recommended PCB geometry are part of the matching solution, so a nearby ST balun code should not be substituted solely because it operates in the same general band.

Quality & Sourcing
Antrex Electronics can support sourcing of BALF-SPI-02D3 for production, repair and shortage requirements. Incoming verification can include manufacturer marking, package dimensions, frequency and impedance review, date-code checks and third-party inspection when requested. For obsolete or NRND parts, the exact ordering suffix should be maintained until an engineering-approved alternative is qualified.
