NJG1739K51
5GHz Band SPDT Switch + LNA GaAs MMIC
I GENERAL DESCRIPTION
The NJG1739K51 is a 5GHz band SPDT switch + low noise amplifier
GaAs MMIC designed for wireless LAN front-end applications.
The NJG1739K51 features low current consumption, low insertion
loss of transmit path and low noise figure of RX LNA mode.
The NJG1739K51 has ESD protection devices to achieve excellent
ESD performances.
A small and ultra-thin package of QFN12-51 is adopted.
