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
