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.
nFEATURES
lLow voltage operation
lLow current consumption
lLow insertion loss
lLow Adjacent Channel
Leakage Power
lUltra small & thin package

DESCRIPTIONS
Positive voltage supply terminal. The positive voltage (+2.7~+5.0V) have to be
supplied. Please connect a bypass capacitor with GND terminal for excellent RF
performance.
2
CTL1
High-impedance C-MOS input terminal. This terminal is set to HighLevel(+2V~VDD) or Low-Level(+0.6V~0V). If the voltage level of this terminal is
unstable, please connect a resistor(100kΩ) with GND terminal or VDD terminal.
4
CTL2
High-impedance C-MOS input terminal. This terminal is set to HighLevel(+2V~VDD) or Low-Level(+0.6V~0V). If the voltage level of this terminal is
unstable, please connect a resistor(100kΩ) with GND terminal or VDD terminal.
5
CTL3
High-impedance C-MOS input terminal. This terminal is set to HighLevel(+2V~VDD) or Low-Level(+0.6V~0V). If the voltage level of this terminal is
unstable, please connect a resistor(100kΩ) with GND terminal or VDD terminal.
6
VSS
Negative voltage supply terminal. Please supply negative voltage of -3.5~-2.0V
on transmitting state. On receiving state, this terminal is internally disconnected,
so the voltage of this terminal(negative, short, or open) does not affect to
receiving signal quality. The bypass capacitor should be connected between this
terminal and GND for excellent RF performance.
8
EXT2
RF receiving port. An external capacitor of 56pF~100pF is required to block DC
voltage (VDD).
10
EXT1
RF transmitting/receiving port. An external capacitor of 56pF~100pF is required
to block DC voltage (VDD).
12
TX
RF transmitting port. An external capacitor of 56pF~100pF is required to block
DC voltage (VDD).
14
TER2
ANT2 termination port. Please connect this port and GND by appropriate
capacitor(10pF) to suppress the interference of ANT1 port signal to ANT2 port.
The capacitor works as DC voltage (VDD) blocking.
15
ANT2
RF receiving port. An external capacitor(56pF~100pF) is required to block DC
voltage (VDD) .
17
ANT1
RF transmitting/receiving port. An external capacitor(56pF~100pF) is required to

PRECAUTIONS
[1] The bypass capacitors should be connected to the VDD, VSS terminals as close as possible
respectively.
[2] For good RF performance, the ground terminals should be directly connected to the ground
patterns and through-holes as close as possible by using relativity wide pattern.
