Detailed Description for HHM1904A1
Product Overview
HHM1904A1 combines controlled single-ended-to-differential conversion with a verified operating range of 2.4 GHz to 2.5 GHz. The 1:1.5 relationship converts the 50 Ω unbalanced / 75 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 dB, phase balance of 180° ±10°.
The device is intended for 2.4 GHz wireless ICs requiring a 75 Ω balanced RF port. Its compact footprint lets the balun sit close to the RFIC, reducing the additional phase error and mismatch introduced by long differential PCB traces. The recorded lifecycle state is Production stopped / legacy, supporting maintenance of an active production BOM.
