H5007 Performance Data
The following graphs typify the scattering (both balanced and unbalanced) and impedance parameters
of the H5007, a magnetic transceiver for long haul gigabit (802.3ab) applications. The H5007
is designed around a 10/100/1000Base-T compliant transformer, having a 1:1 turns ratio and includes
both ser ies and shunt chokes for common mode signal suppression.
S-parameter measurements were taken using a HP8751A network analyzer connected to a HP4380A
cable analyzer and includes S11 and S22, attenuation and phase response for S12 and S21,
differential to common mode rejection, common to common mode rejection ratio, and common
to differential mode rejection.
Z-parameter measurements were taken using a HP4396A network analyzer with a HP43961 RF
impedance test adapter installed, and include Z11, Z22, and the shunt choke’s common mode impedance.
Temperature rise measurements were taken by forcing a variable DC bias through the media
side (secondary) while monitoring the resistance change associated with the primary
winding’s temperature rise.
