1. Fixed Reference. All specified bandwidths and attenuation frequencies are relative to Fc =
240 MHz.
2. Taken at the peak of the response.
3. All attenuation levels are taken to be relative to the level at the response peak.
4. All electrical specifications apply over the whole of the operating temperature range (see
below).
