Notes :
1) All specifications are based on the matching schematic shown below, measured by Agilent Network
analyzer and full 2 port calibration.
2) Electrical margin has been built into the design to account for the variations due to temperature drift
and manufacturing tolerances
3) All attenuation measurements are measured relative to insertion loss
