GENERAL DESCRIPTION
n
PACKAGE OUTLINE
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.

1CTL2 High-impedance C-MOS input terminal. This terminal is set to High-Level by
2V~V
DD
, and Low-Level by +0.6V~0V. In case of open or unstable level,
connect this terminal by 100KΩ resistor with GND terminal or V
DD
terminal.
2CTL3 High-impedance C-MOS input terminal. This terminal is set to High-Level by
2V~V
DD
, and Low-Level by +0.6V~0V. In case of open or unstable level,
connect this terminal by 100KΩ resistor with GND terminal or V
DD
terminal.
3VSS 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.
4EXT2 RF receiving port. An external capacitor of 56pF~100pF is required to block
DC voltage (VDD).
6EXT1 RF transmitting/receiving port. An external capacitor of 56pF~100pF is
required to block DC voltage (VDD).
8TX RF transmitting port. An external capacitor of 56pF~100pF is required to
block DC voltage (VDD).
10 TER2 ANT1 termination port. The influence of ANT1 port to ANT2 port is
suppressed by terminating this port by an appropriate termination. An
external capacitor (5pF) is required to block DC voltage (VDD).
11 ANT1 RF transmitting/receiving port. An external capacitor of 56pF~100pF is
required to block DC voltage (VDD).
13 RX RF receiving port. An external capacitor of 56pF~100pF is required to block
DC voltage (VDD).
15 ANT2 RF receiving port. An external capacitor of 56pF~100pF is required to block
DC voltage (VDD).
17 TER1 ANT2 termination port. The influence of ANT2 port to ANT1 port is
suppressed by terminating this port with appropriate termination. An external
capacitor (5pF) is required to block DC voltage (VDD).
19 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.
20 CTL1 High-impedance C-MOS input terminal. This terminal is set to High-Level by
2V~V

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.
