Detailed Description for HHM1591D1
Product Overview
Designed for 350 MHz to 470 MHz, HHM1591D1 provides a defined balanced RF interface in a compact package. 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 1.5 dB, return loss of 8.5 dB, amplitude balance of 0 dB ±1 dB, phase balance of 180° ±10°.
The operating range is intended for DVB-H, GSM and LTE Bands 31, 72 and 73. 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.
