Notes:
1. Center frequency is defined as the mean of the upper and lower 3dB points. The typical room temperature center
frequency may be offset from 300 MHz to allow for frequency change with temperature.
2. Measured at the frequency at which the insertion loss is minimum.
3. All bandwidths are centered at FC.
4. Decibel level is relative to the insertion loss.
5. Over bandwidth FC +/- 1.2 MHz.
6. These parameters to be satisfied over the 3 dB bandwidth.
