Detailed Description for HHM1591A2
Product Overview
HHM1591A2 is a TDK multilayer chip RF balun transformer characterized from 350 MHz to 950 MHz. The 1:2 transformation connects the 50 Ω unbalanced / 100 Ω balanced ports and replaces a larger discrete matching network. Confirmed selection limits include insertion loss of 2.8 dB, return loss of 4.5 dB, amplitude balance of 0 dB ±2 dB, phase balance of 180° ±20°.
The operating range is intended for Wide sub-GHz cellular and broadcast receiver paths. Related HHM parts use different 50 Ω, 100 Ω, 150 Ω or 200 Ω balanced terminations, so the exact code matters. The recorded lifecycle state is NRND; the exact suffix should remain in the BOM until an approved alternative is qualified.
