NJG1544HC3
2x2 Antenna SWITCH GaAs MMIC
QGENERAL DESCRIPTION
NJG1544HC3 is a 2x2 antenna switch IC designed for the
IEEE 802.11b or 802.11g (2.4GHz band) wireless LAN
application.
This device includes logic decoder function, and can be
operated by 2 bits signal to control Tx/Rx and ANT1/ANT2
switching.
This switch features high isolation and low loss.
The ultra small & ultra thin USB10-C3 package is adopted.
