GENERAL DESCRIPTION
NJG1521PE1 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.
The Ultra small & thin FFP24-E1 package is applied.
