Detailed Description for BALFHB-WL-04D3
Product Overview
BALFHB-WL-04D3 integrates the balanced/unbalanced transformation required in 862 MHz to 928 MHz signal paths. Its network is customized for BGA STM32WL, presenting the stated 50 Ω nominal antenna-side impedance / conjugate match to STM32WL RF pins 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.
This ordering code is tied to BGA STM32WL, low-power mode, 15 dbm and a 4-layer pcb reference layout; using another WL-0xD3 variant changes the validated matching environment. 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 BALFHB-WL-04D3 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.
