Page 7 MLIQ-416 Downconversion Spurious Suppression Spurious data is taken by selecting RF and LO frequencies (+mlo+nrf) within the RF/LO bands, to create a spurious output within the IF band. The mixer is swept across the full spurious band and the mean is calculated. The numbers shown in the table below are for a -1 dbm RF input. Spurious suppression is scaled for different RF power levels by (n- 1), where n is the RF spur order. For example, the 2RFx2LO spur is 61 dbc with an L-Diode for a -1 dbm input, so a - 2 dbm RF input creates a spur that is (2-1) x (-1 db) db lower, or 71 dbc.

The mixer is swept across the full spurious output band and the mean is calculated. The numbers shown in the table below are for a -1 dbm individual IF input, with the unused port terminated in 5 ohms. Spurious suppression is scaled for different IF input power levels by (n-1), where n is the IF spur order. For example, the 2IFx1LO spur is typically 64 dbc with an L-Diode for a -1 dbm input, so a dbm IF input creates a spur that is (2-1) x (-1 db) db lower, or 74 dbc.
