LDB15829AAD1A030

Product Overview

Designed around 699 MHz to 960 MHz, LDB15829AAD1A030 provides the stated balanced RF interface in a compact production package. 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 1.35 dB maximum at 25°C; 1.45 dB over the stated temperature range, return loss of 8.54 dB minimum.

The operating span supports Low-band cellular, LTE and sub-GHz differential 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 Exact compact low-band code, so the part is principally relevant to legacy production, repair and shortage sourcing.

Quality & Sourcing

Antrex Electronics can support sourcing of LDB15829AAD1A030 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.
