rfplot

Create an IMT mixer with the LO frequency of 5995 MHz and with the IMT spurs.

imt = mixerIMT(LO=5995e6,IMT=...
     [99 17 13.6 42.9; 40 0 47.7 54.3; 50.4 58.5 61.3 72.2; 75 67.4 75 99]);

Plot the mixer spur at an input signal frequency of 1005 MHz.

rfplot(imt,1005e6)

Create an IMT mixer with 4-by-4 IMT spur data.

imt = mixerIMT(LO=5995e6,IMT=...
     [99 17 11.6 42.9; 40 0 44.7 54.3; 51.4 58.5 61.3 72.2; 75 67.4 73 99]);

Create an IMT mixer with 3-by-3 IMT spur data.

imt2 = mixerIMT(LO=5995e6,IMT=...
     [99 99 80; 99 0 99; 99 80 99]);

Type these commands at the command line to create a rfplot figure with two tabs. Add axes to each tab by specifying the parent container for each axis. Plot the IMT mixer with the 4-by-4 IMT spur data in the first tab and the IMT mixer with the 3-by-3 IMT spur data in the second tab.

figure
tab1 = uitab('Title','4-by-4 IMT spur data');
ax3 = axes(tab1);
rfplot(ax3,imt,1005e6)

tab2 = uitab('Title','3-by-3 IMT spur data');
ax4 = axes(tab2);
rfplot(ax4,imt2,1005e6)

Since R2024a

Create a mixerIMT object and specify the IMT data.

m = mixerIMT(IMT= [99 17 11.6; 40 0 44.7; 51.4 58.5 61.3]);

Specify the RF bandwidth as 120 MHz and the IF bandwidth as 10 MHz as inputs to the rfplot function in order to visualize the spur and spur-free zones of the mixerIMT object.
