NJG1515AVB2
TDMA ANTENNA SWITCH GaAs MMIC
nGENERAL
DESCRIPTION
NJG1515AVB2 is an antenna switch IC for a digital cellular
phone of 800MHz and 1.5GHz band.
The parallel control signals of three bits connect T/R circuits
to internal two antennas or external two antennas.
The termination ports with external matching circuits make
low interference between diversity antennas.
NJG1515AVB2 features very low insertion loss and low
current consumption in a very small SSOP20 package.
