GNSS LOW NOISE AMPLIFIER NJG8HA8 GENERAL DESCRIPTION The NJG8HA8 is a low noise amplifier GaAs MMIC designed for GNSS (Global Navigation Satellite Systems). This amplifier provides low noise figure, high gain and high IP operated by single low positive power supply. This IC has the function of Stand-by mode. The NJG8HA8 can be tuned to wide frequency from.ghz to.7ghz by changing the external matching components. An ultra-small and ultra-thin package of the USB-A8 is adopted.

NJG8HA8 TERMINAL INFORMATION No. SYMBOL DESCRIPTION VINV Power supply pin of the inverter circuit. RFOUT RF Output and voltage supply pin. External matching circuits and a bypass capacitor is required. L is a RF choke inductor. These elements are used as output matching circuit. GND Ground pin. To keep good RF grounding performance, please use multiple via holes to connect with ground plane and this pin.) RFIN RF input pin. A DC blocking capacitor is not required. An external matching circuit is required. GND VCTL Ground pin. To keep good RF grounding performance, please use multiple via holes to connect with ground plane and this pin.) 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. CAUTION ) Ground terminal (, ) should be connected to the ground plane as low inductance as possible. - -
