The decouping capacitors between GND Pin and VCC Pin should be as close to the IC as possible. 2) The resistors connected to Pins 9 and 10 should be as close to the IC as possible. 3) This IC assumes the excellent characteristics when the differential input impedance between Pins 1 and 2 is 500 Ω. Refer to the Measurement Circuit for the external element settings, etc. 4) Pay attention to handling this IC because its electrostatic discharge strength is weak. —8— CXA3202AN Sensitivity 40 VCC = 3.0V 20 0 10 15 IIP3 VCC = 3.0V Power gain [dB] 5 –20 –40 –60 –80 –100 0 0.5 1 1.5 2 2.5 3 3.5 Vgctl [V] IIP3 [dBm] 0 –5 T = –40°C T = 27°C T = 85°C T = –40°C T = 27°C T = 85°C –10 –15 –60 –40 –20 0 20 40 Power gain [dB] Noise Figure 100 90 80 VCC = 3.0V 4 6 Gain Error from Room Temp VCC = 3.0V Noise figure [dB] 70 60 50 40 30 20 –80 Gain error [dB] T = –40°C T = 27°C T = 85°C –60 –40 –20 0 20 2 0 –2 T = –40°C T = 85°C –4 –6 –80 –60 –40 –20 0 20 40 Power gain [dB] Power gain [dB] —9— CXA3202AN Package Outline Unit : mm 16PIN SSOP (PLASTIC) ∗5.0 ± 0.1 + 0.2 1.25 – 0.1 0.1 16 9 A ∗4.4 ± 0.1 1 8 0.65 + 0.05 0.15 – 0.02 + 0.1 0.22 – 0.05 0.13 M 0.1 ± 0.1 0° to 10° DETAIL A NOTE: Dimension “∗” does not include mold protrusion.
