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  
4) Insertion Loss is minimum loss within passband at ambient temperature with matching network  
5) from 10 MHz to 68.5 MHz and from 73.5 MHz to 130 MHz
