Detailed Description for HHM1522B1
Product Overview
HHM1522B1 combines controlled single-ended-to-differential conversion with a verified operating range of 880 MHz to 960 MHz. 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 1.3 dB maximum, return loss of 12 dB minimum, amplitude balance of 0 dB ±1 dB, phase balance of 180° ±10°.
The operating span supports GSM900, UMTS, LTE and 5G Band 8/81 balanced 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 NRND; the exact ordering code should remain in the approved BOM until an engineering-qualified alternative is available.

Quality & Sourcing
Antrex Electronics can support sourcing of HHM1522B1 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.
