NJG1104KB2 800MHz BAND LNA GaAs MMIC nGENERAL DESCRIPTION NJG1104KB2 is a variable gain low noise amplifier (LNA). At 800MHz band, noise figure is 1.2dB, variable gain range is 21dB and input 3rd order intercept point is +6dBm. These characteristics are very suitable for CDMA cellular phone application. The variable attenuators placed in front of LNA realize wide range of input power with low distortion. Very small and thin FLP6-B2 package is adopted. nFEATURES lLow voltage operation lLow current consumption lHigh gain lLow noise figure lVariable gain control lHigh input IP3 lHigh output IP3 lUltra small & ultra thin package nPACKAGE OUTLINE NJG1104KB2 +2.8V typ. 6.0mA typ. 15dB typ. @f=865MHz 1.2dB typ. @f=865MHz 21dB typ. @f=865MHz,VCONT=0.2 to 1.7V +6dBm typ. @f=865.0+865.1MHz, Pin=-30dBm +21dBm typ. @f=865.0+865.1MHz, Pin=-30dBm FLP6-B2 (Mount Size: 2.1x2.0x0.75mm) nPIN CONFIGURATION KB2 Type (Top View) 3 4 AMP 5 2 ATT 6 Note: The 1 Pin Connection 1.SOURCE 2.GND 3.RFout 4.GND 5.VCONT 6.RFin portion above shows orientation mark printed on the package surface. -1- NJG1104KB2 nABSOLUTE MAXIMUM RATINGS PARAMETER Drain Voltage Gain Control Voltage Input Power Power Dissipation Operating Temperature Storage Temperature ( Ta=25°C, Zs=Zl=50Ω ) RATINGS UNITS 6.0 V 4.0 V +20 dBm 450 mW -40~+85 °C -55~+125 °C SYMBOL CONDITIONS VDD VCONT Pin VDD=2.8V PD Topr Tstg nELECTRICAL CHARACTERISTICS PARAMETER Operating Frequency Drain Voltage Gain Control Voltage Operating Current Gain Control Terminal Current Small Signal Gain Gain Flatness Gain Control Range Noise Figure Pout at 1dB Gain Compression point Output 3rd Order Intercept Point Input 3rd Order Intercept Point 1 Input 3rd Order Intercept Point 2 RF Input Port VSWR RF Output Port VSWR -2- (VDD =2.8V, VCONT=1.7V, f=865MHz, Ta=25°C, Zs=Zl=50Ω ) SYMBOL CONDITIONS MIN TYP MAX UNITS freq 830 865 900 MHz VDD 2.7 2.8 5.5 V VCONT 0.2 1.7 3.0 V IDD No RF Signal 6.0 7.5 mA ICONT No RF Signal Gain Gflat GCONT NF f=830~900MHz VCONT=0.2V, 1.7V P-1dB OIP3 IIP3-1 IIP3-2 VSWRi VSWRo f=865.0+865.1MHz Pin=-30dBm f=865.0+865.1MHz Pin=-30dBm f=865.0+865.1MHz Pin=-10dBm VCONT =0.2V - 1.0 5.0 uA 13.0 18.5 - 15.0 0.5 20.5 1.20 17.0 1.0 22.5 1.40 dB dB dB dB - +8.0 - dBm +19.0 +21.0 - dBm +4.0 +6.0 - dBm +21.0 +26.0 - dBm - 1.5 1.5 2.0 2.0 - NJG1104KB2 nTERMINAL INFORMATION Pin 1 Function Description This terminal is internally connected to FET’s source of LNA.
