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) This IC assumes the excellent characteristics when the differential input impedance between Pins 5 and 7 is 500, and the differential output impedance between Pins 17 and 19 is 1k. Refer to the Measurement Circuit for the external element settings, etc. 3) Connect the capacitors, which are connected to Pins 12 and 13, to Pin 14 (GND2). 4) Pay attention to handling this IC because its electrostatic discharge strength is weak. -9- CXA3002N 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 T = -40deg T = 25deg T = 85deg -40 -20 0 Power gain [dB] 20 40 60 -50 -60 -60 - 10 - CXA3002N Noise Figure 50 VCC = 3.6V 40 T = -40deg T = 25deg T = 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 T = -40deg T = 85deg 2 Gain error [dB] 0 -2 -4 -6 -60 -40 -20 0 Power gain [dB] 20 40 60 - 11 - CXA3002N Package Outline Unit: mm 24PIN SSOP (PLASTIC) 275mil 7.8 0.1 24 13 + 0.2 1.25 - 0.1 0.10 A 0.1 0.1 5.6 0.1 7.6 0.2 0 to 10 1 + 0.1 0.22 - 0.05 12 + 0.05 0.65 0.12 0.15 - 0.02 DETAIL A NOTE : NOT INCLUDE MOLD FINS.
