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, Pins 4 and 5 is 500. 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- CXA3201AN Sensitivity 60 VCC = 3.0V 40 20 -10 0 IIP3 VCC = 3.0V Power gain [dB] -20 0 -20 -40 -60 -80 0 0.5 1 1.5 Vgctl [V] 2 2.5 3 IIP3 [dBm] -30 -40 T = -40C T = 27C T = 85C T = -40C T = 27C T = 85C -50 -60 -80 -60 -40 -20 0 20 40 60 Power gain [dB] Noise Figure 25 VCC = 3.0V 20 4 6 Gain Error from Room Temp VCC = 3.0V Noise figure [dB] 15 Gain error [dB] 2 0 10 -2 T = -40C T = 85C 5 T = -40C T = 27C T = 85C 0 10 20 30 40 50 60 -4 0 -10 -6 -80 -60 -40 -20 0 20 40 60 Power gain [dB] Power gain [dB] -9- CXA3201AN 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.
