11. GRAPHS
The following graphs are only for a typical sample measured on a SA2411 test board under nominal condition applying an 11Mb/s CCK 802.11b
modulation. Corrections for input, output and supply losses have been applied. The dotted lines represent the low gain mode. The solid
lines are for the high gain mode.
The first two graphs are small signal graphs. The gain and the DC currents are plotted versus supply voltage.
