Measured over passband, excluding fi nal 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.
