New Release: HBBL250-600V4 Broadband Tissue Simulating Liquid

SPEAG is closing the broadband Tissue Simulating Liquid (TSL) gap with the new HBBL250–600V4 for Specific Absorption Rate (SAR) testing in the frequency range from 250 – 600 MHz.

Fully compliant with IEC/IEEE 62209-1528, the dielectric properties of HBBL250–600V4 are ensured within a tolerance of ±10%, enabling accurate and reliable measurement of SAR. In addition, optimization for TETRA and LTE/NR low-band devices guarantees a convenient, efficient solution for testing professional and consumer products.

With the addition of HBBL250–600V4 to HBBL4–250V3 and HBBL600–10000V6, SPEAG TSLs now cover the frequency range of 4 MHz – 10 GHz with just three liquids — reducing setup changes and simplifying testing operations.
