NJG9UA UHF BAND LOW NOISE AMPLIFIER GaAs MMIC GENERAL DESCRIPTION The NJG9UA is a low noise amplifier GaAs MMIC designed for mobile digital TV application (7~77 MHz). This IC has a LNA pass-through function to select high gain mode or low gain mode by single bit control. Also, the ESD protection circuit is integrated into the IC to achieve high ESD tolerance. An ultra-small and ultra-thin package of EPFFP6-A is adopted.
