Detailed Description for LDB21942M10C-001
Product Overview
LDB21942M10C-001 is intended for Centered at 942 MHz for the 925-960 MHz application band signal chains where a compact transformer or matched balun replaces a larger discrete network. The 1:2 relationship converts the 50 Ω unbalanced / 100 Ω balanced ports and establishes the differential load expected by the connected RF stage. Only the confirmed operating band, impedance relationship, package and intended application are included.
The operating span supports GSM900 and low-band cellular RFICs requiring a 100 Ω balanced port. The transformer ratio, center-tap arrangement and port impedance should be evaluated together rather than selecting a replacement from frequency overlap alone. The recorded lifecycle state is Obsolete / legacy exact model, so the part is principally relevant to legacy production, repair and shortage sourcing.

Quality & Sourcing
Antrex Electronics can support sourcing of LDB21942M10C-001 for production, repair and shortage requirements. Incoming verification can compare the exact manufacturer marking, ordering suffix, package dimensions, frequency range, single-ended and balanced impedances, insertion-loss limits and lifecycle status. For obsolete or NRND devices, Antrex Electronics can also coordinate BOM sourcing and third-party inspection before shipment, while alternative parts should remain subject to engineering approval for PCB footprint, impedance and RF performance.
