ETAL P3801 变压器, V.34+/V90
The is a Line Matching Transformer intended for high-speed applications where low distortion at moderate power levels and very low voice band frequencies is required. At moderate power levels 10Bm performance to V.90/V.92 may be achieved. It has extended flat frequency response from 30 to 4kHz with very low levels of signal distortion at signal frequencies as low as 150Hz. P3801 is electrically and mechanically compatible with P3034 and P2001 for supplementary insulation 250V working applications and directly replaces 9002VF, 671-8236M, MTLM 2001, EMIT-2001 and ATS-091/B without changes to matching components, but with the added benefit of considerably improved thermal stability. P3801 also offers a drop-in performance upgrade path for P3800 and P1200. P3801 uses patented design and construction methods to achieve excellent signal performance and safety isolation to international standards.
