NOTES:
1. With simple external matching
2. With 50 pF coupling capacitors on all RF and IF parts
3. This part has been optimized for the stated frequency range. Operation outside this frequency range may yield performance other than
specified in this datasheet.
4. Measured 5dB lower than 1dB compression point, with typical output matching network.
5. Measured at 1dB compression point.
6. With typical output matching network (no image reject mixer is used).
