5.3 Output Spectrum
The most significant spurious RF outputs of the OL2300 as measured at the RF output
connector are shown in Figure 6
to Figure 9. The spectrum analyzer is connected directly
to the evaluation board. The spectrum analyzer settings can be seen. Measurements are
made under conditions: CW, VCC = 2.7 V, AMH = 15.
5.3.1 315 MHz
Plot (1) is efficiency CASC = 0, ENRAD = 0
Plot (2) is efficiency CASC = 1, ENRAD = 1
Plot (3) is output power CASC = 0, ENRAD = 0
Plot (4) is output power CASC = 1, ENRAD = 1
