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