H5004 Performance Data
The following graphs typify the scattering (both balanced and unbalanced) and impedance
parameters of the H5004, a magnetic transceiver for long haul gigabit (802.3ab) applications. The
H5004 is designed around a 10/100/1000Base-T compliant transformer, having a 1:1 tur ns ratio
and includes a series choke 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
inpedance test adapter installed, and include Z11 and Z22.
Temperature rise measurements were taken by forcing a var iable DC bias through the media
side (secondar y) while monitoring the resistance change associated with the primary winding’s
temperature rise.
