Consult factory. 2For non-connectorized packages, specify I-port configuration by adding –1 or –2 suffix to model number. Default is –2 configuration when not specified. The T3H-18G is a high performance mixer featuring LO/RF from 10 MHz to 18 GHz and IF from 10 MHz to 18 GHz. As with all T3 mixers, this mixer offers unparalleled nonlinear performance in terms of IIP3, P1dB, and spurious performance with a flexible LO drive requirement from +15 dBm to +25 dBm. The T3H-18G is offered in connectorized, surface mount, and drop-in style packaging, suitable for any type of system level integration. The T3H-18G is a form-fit-function replacement for the obsolete T3H-18, built using GaAs diodes instead of Si. The ADM1- 0026PA and ADM2-0035PA are recommended as the ideal LO driver for the T3H-18G, and for a list of recommended LO driver amps for all mixers and IQ mixers, see here.

A TWO-TONE-TERMINATOR MIXER T3H-18G Page 5 LO/RF 10 MHz to 18 GHz IF 10 MHz to 18 GHz Downconversion Spurious Suppression Spurious data is taken by selecting RF and LO frequencies (+mLO+nRF) within the 10 MHz to 18 GHz RF/LO bands, which create a 100 MHz IF spurious output. The mixer is swept across the full spurious band and the mean is calculated. The numbers shown in the table below are for a -10 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 for a -10 dBm input, so a -20 dBm RF input creates a spur that is (2-1) x (-10 dB) dB lower, or 71 dBc. Spurious suppression is the same for both diode options. Typical Downconversion Spurious Suppression (dBc): Square Wave (Sine Wave) LO6 -10 dBm RF Input 0xLO 1xLO 2xLO 3xLO 4xLO 5xLO 1xRF 17 (18) Reference 19 (27) 10 (11) 19 (34) 16 (18) 2xRF 60 (59) 65 (60) 61 (57) 65 (62) 63 (53) 64 (55) 3xRF 101 (96) 85 (75) 92 (86) 88 (81) 97 (92) 90 (76) 4xRF >110 >110 >110 >110 >110 >110 5xRF >120 >120 >120 >120 >120 >120 A sample downconversion spurious sweep is shown below. An LO which is 100 MHz higher than the RF is used to create a 100 MHz reference IF. A second LO is used to create a 2x2 spurious IF, also at 100 MHz (50 MHz fundamental IF). The difference between these two output levels is the spurious suppression in dBc. The mean value across the full 10 MHz to 18 GHz RF input band is the number shown in the table above. Downconversion 2RFx2LO Spurious Data Example: RF Input: 10 MHz to 18.0 GHz @ -10 dBm LO for Reference: 110 MHz to 18.1 GHz LO for Spurious: 60 MHz to 18.05 GHz IF Output: 100 MHz

A TWO-TONE-TERMINATOR MIXER T3H-18G Page 6 LO/RF 10 MHz to 18 GHz IF 10 MHz to 18 GHz Upconversion Spurious Suppression Spurious data is taken by mixing a 100 MHz IF with LO frequencies (+mLO+nIF), which creates an RF within the 10 MHz to 18 GHz RF 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 -10 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 2IFx1LO spur is typically 60 dBc for a -10 dBm input, so a -20 dBm IF input creates a spur that is (2-1) x (-10 dB) dB lower, or 70 dBc. Spurious suppression is the same for both diode options. Typical Upconversion Spurious Suppression (dBc): Square Wave (Sine Wave) LO6 -10 dBm IF Input 0xLO 1xLO 2xLO 3xLO 4xLO 5xLO 1xIF 18 (17) Reference 18 (22) 11 (11) 18 (27) 16 (18) 2xIF 62 (62) 60 (54) 60 (49) 67 (55) 61 (48) 64 (52) 3xIF 73 (72) 86 (72) 95 (78) 90 (66) 95 (69) 91 (65) 4xIF >110 >110 >110 >110 >110 >110 5xIF >120 >120 >120 >120 >120 >120 A sample upconversion spurious sweep is shown below. A 100 MHz reference IF input is used to create an RF output that is 100 MHz below the LO input (LO-IF=RF). A second LO (100 MHz higher) is combined with the same 100 MHz IF input (LO-2xIF=RF) to create the same 10 MHz to 18 GHz RF output band. The difference between these two output levels is the spurious suppression in dBc. The mean value across the full RF output band is the number shown in the table above. Upconversion 2IF x 1LO Spurious Data Example: IF Input: 100 MHz @ -10 dBm LO for Reference: 110 MHz to 18.1 GHz LO for Spurious: 210 MHz to 18.2 GHz RF Output: 10 MHz to 18 GHz
