HHM1908A1 詳細描述
Product Overview
The HHM1908A1 is a TDK multilayer or wound surface-mount RF balun transformer optimized for 4.9 GHz to 5.95 GHz front ends. The 1:2 relationship converts the 50 Ω unbalanced / 100 Ω balanced ports and establishes the differential load expected by the connected RF stage. Confirmed selection data includes insertion-loss performance of 0.8 dB maximum, return loss of 10 dB minimum, amplitude balance of 0 dB ±2.5 dB, phase balance of 180° ±10°.
The band is aligned with 5 GHz WLAN 50 Ω-to-100 Ω differential RFIC interfaces. At 5 GHz, short and symmetrical balanced traces, controlled ground geometry and the manufacturer land pattern are important to preserving phase and insertion-loss performance. The recorded lifecycle state is Obsolete, so the part is principally relevant to legacy production, repair and shortage sourcing.

Quality & Sourcing
Antrex Electronics can support sourcing of HHM1908A1 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.
