1 MEDIUM POWER AMPLIFIER GaAs MMIC GENERAL DESCRIPTION NJG132V 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 2dB dynamic range. NJG132V 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. PACKAGE OUTLINE NJG132V FEATURES Voltage gain under low distortion Low voltage operation Low current consumption High gain Low distortion (ACP) Reduction of Parasitic oscillation Input and output internal matching circuit Package +3.V typ. 195mA P OUT =21dBm 32dB -6dBc P OUT =21dBm SSOP14 (Package size: 5.x6.4x1.25mm) PIN CONFIGURATION V Type (Top View) Pin connection 1.
