Figure 17. LNA/Mixer IIP3, VDD = 3.0 V, Temperature = 25°C, RF = 915 MHz,

LNA Gain = High, Mixer Gain = High, Source 1 Frequency =

915 MHz + 0.4 MHz, Source 2 Frequency = 915 MHz + 0.7 MHz

Figure 18. IF Filter Profile vs. IF Bandwidth, VDD = 3.0 V, Temperature = 25°C

Figure 19. IF Filter Profile vs. VDD and Temperature, 100 kHz IF Filter Bandwidth

(Minimum Recommended VDD = 2.2 V, 1.8 V Operation Shown for Robustness)
