Notes:

2. Maximum gain deviation within passband with ground paddle temp. range of -20°C to +85°C relative to +45°C.

3. Peak deviation from straight line across full band.

4. Max slope of best fit straight line over all attenuator settings.

5. Production tested at 66 MHz, 330 MHz, and 990 MHz.

6. Adjacent channel (750 kHz from channel block edge to 6 MHz from channel block edge) better than -60 dBc.

7. Next-adjacent channel (6 MHz from channel block edge to 12 MHz from channel block edge) better than -63 dBc.

8. Third-adjacent channel (12 MHz from channel block edge to 18 MHz from channel block edge) better than -65 dBc.

9. In each of 2N contiguous 6 MHz channels or in each of 3N contiguous 6 MHz channels coinciding with 2

harmonic components, respectively (up to 1002 MHz) better than -63 dBc.

10. 150 MHz tone spacing at 8 dBm/tone.
