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.

DESCRIPTIONS
CTL2
High-impedance C-MOS input terminal. This terminal is set to High-Level by
2V~VDD, and Low-Level by +0.6V~0V. In case of open or unstable level,
connect this terminal by 100KΩ resistor with GND terminal or VDD terminal.
2
CTL3
High-impedance C-MOS input terminal. This terminal is set to High-Level by
2V~VDD, and Low-Level by +0.6V~0V. In case of open or unstable level,
connect this terminal by 100KΩ resistor with GND terminal or VDD terminal.
Negative voltage supply terminal. The negative voltage (-3.5~-2.0V) have to
be supplied on transmitting. Otherwise negative voltage of -2.5~0V can be
used or this terminal can be stayed open, because internal level of this
terminal is automatically set to GND level on receiving. The bypass capacitor
have to be connected with GND terminal for excellent RF performance.
RF receiving port. An external capacitor of 56pF~100pF is required to block
DC voltage (VDD).
RF transmitting/receiving port. An external capacitor of 56pF~100pF is
required to block DC voltage (VDD).
RF transmitting port. An external capacitor of 56pF~100pF is required to
block DC voltage (VDD).

Positive voltage supply terminal. The positive voltage (2.7~5.0V) have to be
supplied. The bypass capacitor have to be connected with GND terminal for
excellent RF performance.

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 using relatively wide pattern.
