Detailed Description for LDB21942M05C-001
Product Overview
For RF paths operating across 925 MHz to 960 MHz, LDB21942M05C-001 establishes the published impedance and balance relationship. The unity-ratio network preserves the nominal 50 Ω unbalanced / 50 Ω balanced relationship while converting between single-ended and balanced circuitry. Confirmed selection data includes insertion-loss performance of 1.5 dB maximum.
The operating span supports GSM900, UMTS, LTE and narrow low-band receiver interfaces. 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 The recorded lifecycle state is Obsolete / not for new design, so the part is principally relevant to legacy production, repair and shortage sourcing.

Quality & Sourcing
Antrex Electronics can support sourcing of LDB21942M05C-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.
