Separate Pin 3 (GND1) and Pin 14 (GND2) to prevent interference between input and output. Furthermore, the decoupling capacitors between Pins 2 and 3, Pins 14 and 15 should be as close to the IC as possible. 2) The resistors connected to Pins 17 and 19 should be as close to the IC as possible. 3) This IC assumes the excellent characteristics when the differential input impedance between Pins 5 and 7, Pins 9 and 11 is 500. Refer to the Measurement Circuit for the external element settings, etc. 4) Connect the capacitors, which are connected to Pins 12 and 13, to Pin 14 (GND2). 5) Pay attention to handling this IC because its electrostatic discharge strength is weak. -9- CXA3001N Sensitivity 60 VCC = 3.6V 40 20 Power gain [dB] 0 -20 -40 T = -40deg T = 25deg T = 85deg -60 0 0.5 1 1.5 2 2.5 3 3.5 VGCTL [V] IIP3 0 VCC = 3.6V -10 -20 IIP3 [dBm] -30 -40 Ta = -40deg Ta = 25deg Ta = 85deg -40 -20 0 Power gain [dB] 20 40 60 -50 -60 -60 - 10 - CXA3001N Noise Figure 50 VCC = 3.6V 40 Ta = -40deg Ta = 25deg Ta = 85deg Noise figure [dB] 30 20 10 0 -60 -40 -20 0 Power gain [dB] 20 40 60 Gain Error from Room Temp. 6 VCC = 3.6V 4 Ta = -40deg Ta = 85deg 2 Gain error [dB] 0 -2 -4 -6 -60 -40 -20 0 Power gain [dB] 20 40 60 - 11 - CXA3001N Package Outline Unit: mm 24PIN SSOP(PLASTIC) + 0.2 1.25 - 0.1 7.8 0.1 0.1 13 24 A 1 + 0.1 0.22 - 0.05 12 + 0.05 0.15 - 0.02 0.65 0.1 0.1 0.13 M 5.6 0.1 0 to 10 NOTE: "" Dimensions do not include mold protrusion.
