Page 5 ML1-11SM / 1.5 to 1 GHz Downconversion Spurious Suppression Spurious data is taken by selecting and frequencies (+m+n) within the / 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 input. Spurious suppression is scaled for different power levels by (n- 1), where n is the spur order. For example, the 2x2 spur is 68 dbc for the H-diode version for a -1 dbm input, so a -2 dbm input creates a spur that is (2-1) x (-1 db) db lower, or 78 dbc. ical Downconversion Spurious Suppression (dbc): H-diode (L-diode) 5-1 dbm Input x 1x 2x 3x 4x 5x 1x 18 (18) Reference 29 (31) 12 (11) 3 (31) 25 (23) 2x 68 (63) 55 (49) 68 (59) 56 (48) 65 (59) 54 (51) 3x 9 (75) 66 (5) 79 (65) 72 (56) 8 (64) 7 (54) 4x 96 (87) 112 (86) 19 (88) 17 (83) 111 (93) 16 (85) 5x 112 (96) 119 (91) 126 (99) 119 (84) 129 (12) 122 (93) Upconversion Spurious Suppression Spurious data is taken by mixing an input within the IF band, with frequencies (+m+nif), to create a spurious output within the output band. 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 IF input. Spurious suppression is scaled for different IF input power levels by (n-1), where n is the IF spur order. For example, the 2IFx1 spur is typically 68 dbc for the H-diode version for a -1 dbm input, so a -2 dbm IF input creates a spur that is (2-1) x (-1 db) db lower, or 78 dbc. ical Upconversion Spurious Suppression (dbc): H-diode (L-diode) 5-1 dbm IF Input x 1x 2x 3x 4x 5x 1xIF 13 (14) Reference 29 (3) 11 (11) 29 (32) 2 (2) 2xIF 57 (51) 68 (61) 55 (5) 58 (53) 42 (38) 58 (54) 3xIF 89 (75) 74 (61) 81 (69) 65 (53) 71 (6) 62 (5) 4xIF 117 (98) 113 (94) 16 (9) 11 (92) 88 (77) 95 (88) 5xIF 132 (115) 118 (93) 124 (18) 11 (91) 116 (1) 12 (92)
