NJG1108HA8 GPS LOW NOISE AMPLIFIER GaAs MMIC ! GENERAL DESCRIPTION The NJG1108HA8 is a low noise amplifier GaAs MMIC designed for GPS. This amplifier provides low noise figure, high gain and high IP3 operated by single low positive power supply. This IC has the function of Stand-by mode. This amplifier can be tuned to wide frequency point (1.5GHz~2.7GHz) by changing the external matching components. An ultra-small and ultra-thin package of the USB6-A8 is adopted. ! FEATURES " Low voltage operation " Low current consumption " High gain " Low noise figure " Input power at 1dB gain compression point " High input IP3 " Ultra-small and ultra-thin package !

External matching circuits and a bypass capacitor is required. L3 is a RF choke inductor. These elements are used as output matching circuit. 3 GND Ground pin. To keep good RF grounding performance, please use multiple via holes to connect with ground plane and this pin.) 4 RFIN RF input pin. A DC blocking capacitor is not required. An external matching circuit is required. 5 GND Ground pin. To keep good RF grounding performance, please use multiple via holes to connect with ground plane and this pin.) 6 VCTL Control voltage input pin. This control pin is set to high. LNA suffers from standby state when LNA puts the changeover voltage of "Low" in a state of movement when the changeover voltage of "High" is put in this terminal. Power supply pin of the inverter circuit. CAUTION 1) Ground terminal (3, 5) should be connected to the ground plane as low inductance as possible. -4- NJG1108HA8 !
