| NJG1302V MEDIUM POWER AMPLIFIER GaAs MMIC nGENERAL DESCRIPTION NJG1302V is a GaAs MMIC designed mainly for the final stage power amplifier of Japanese PHS handset, but suitable digital wireless phone and wireless LAN. This amplifier has wide variable gain capability of 20dB dynamic range. NJG1302V has input and output matching circuits internally and features low voltage and high efficiency operation. The output power of 21dBm is easily available with very low distortion. nPACKAGE OUTLINE NJG1302V nFEATURES lVoltage gain under low distortion lLow voltage operation lLow current consumption lHigh gain lLow distortion(ACP) lReduction of Parasitic oscillation lInput and output internal matching circuit lPackage +3.0V typ. 195mA typ. @f= 1.9GHz, Pout= 21dBm 32dB -60dBc typ. @f= 1.9GHz, POUT= 21dBm SSOP14 nPIN CONFIGURATION V Type (Top View) 14 13 12 11 10 9 8 Pin Connection 1.
