1 LOW NOISE AMPLIFIER GaAs MMIC GENERAL DESCRIPTION NJG7HB6 is a Low Noise Amplifier GaAs MMIC designed for GPS This amplifier provides low noise figure, high gain and high IP operated by single low positive power supply. This amplifier includes internal self-bias circuit and input DC blocking capacitor. This amplifier can be tuned to wide frequency point (.GHz~.GHz). An ultra small and ultra thin package of USB-B6 is adopted. PACKAGE OUTLINE NJG7HB6 FEATURES Low voltage operation Low current consumption High small signal gain Low noise figure High Input IP Ultra small & ultra thin package +.7V typ..ma typ. 7dB -.dbm USB-B6 (Package size:.x.x.mm) PIN CONFIGURATION HB6 Type (Top View) 6 7 A MP Pin Connection.RF OUT.N/C.EXTCAP.N/C.N/C 6.GND 7.
