| NJG1521PE1 TDMA ANTENNA SWITCH GaAs MMIC nGENERAL 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. nPACKAGE OUTLINE NJG1521PE1 nFEATURES lLow voltage operation lLow current consumption lLow insertion loss lLow Adjacent Channel Leakage Power lUltra small & thin package nPIN CONFIGURATION -2.5V(TX only) and +3.5V 10A Typ.(TX Mode, Pin=30dBm) 2A Typ.(RX Mode, No RF Signal) 0.45dB Typ. @(TX-ANT1, TX-EXT1) fin=940MHz, Pin=30dBm 0.55dB Typ. @(TX-ANT1, TX-EXT1) fin=1453MHz, Pin=30dBm -63dBc Typ. @ VDD=+3.5V, VSS=-2.5V, fin=940MHz, Pin=30dBm -64dBc Typ. @VDD=+3.5V, VSS=-2.5V, fin=1453MHz, Pin=30dBm FFP24-E1 (Mount Size: 3.5x3.5x0.85mm) FFP24 Type (Top View) Pin Connection 6 7 5 4 3 2 1 24 1.
