This data shows the MASW-008543 measured on
an evaluation board with 0 Ω resistors. The board
and connector loss have been removed.
0 Ω resistors can be used if negative control is
available. To avoid changing the device bias
points, the device should not be exposed to DC
potentials on the RF ports.
With positive control MACOM recommends using
DC-Blocking capacitors large enough that their
Xc is insignificant at the frequency of use. At
50 MHz a capacitor value greater than 1000 pF is
recommended.
