1. Measured over passband, excluding final roll-offs to the 1 dB points. The amplitude
ripple includes ripple (fast variations) and slope (slow variations).
2. Taken relative to mean level over a 135.6 to 144.4 MHz frequency interval.
3. Evaluated over a 135.315 to 144.685 MHz frequency interval.
4. All electrical specifications apply over the full operating temperature range.
