Detailed Description for HHM1589D1
Product Overview
HHM1589D1 is intended for 350 MHz to 950 MHz front ends that require a compact production-ready balun. The 1:4 transformation connects the 50 Ω unbalanced / 200 Ω balanced ports and replaces a larger discrete matching network. Confirmed selection limits include insertion loss of 2.6 dB, return loss of 5 dB, amplitude balance of 0 dB ±2 dB, phase balance of 180° ±20°.
The operating range is intended for Wide sub-GHz DVB-H, GSM, LTE and 5G front ends. 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 EOL announced; the exact suffix should remain in the BOM until an approved alternative is qualified.
