DESCRIPTION
P3801 intended high-speed applications where distortion moderate power levels very voiceband frequencies required most competitive price. moderate power levels (e.g. -10dBm) performance V.90/V.92 achieved. P3801 extended flat frequency response from 30Hz 4kHz with very levels signal distortion signal frequencies 150Hz. P3801 electrically mechanically compatible with P3034 P2001 supplementary insulation 250V working applications, directly replaces 9002VF, 671-8236M, MTLM 2001, EMIT-2001, ATS-091/B without changes matching components, with added benefit considerably improved thermal stability. P3801 also offers drop-in performance upgrade path P3800 P1200. P3801 uses patented design construction methods achieve excellent signal performance safety isolation international standards truly cost. P3801 certified 60950, 950, UL1950 41003. P3801 Recognized Component supported BABT Certificate Recognition Test Certificate.

Figure gives flat responses against CTR21 complex reference impedance (typically around ±0.5dB 300Hz 3.4kHz). Return loss typically better than 20dB. circuit values parentheses give optimum flatness small sacrifice return loss. circuits with existing board drillings, figure gives good return loss (>20dB) flatness against CTR21 complex reference impedance, flatness degraded this topology.
