NJG1524APC1
DPDT SWITCH GaAs MMIC
nGENERAL
DESCRIPTION
NJG1524APC1 is a DPDT switch GaAs MMIC.
The two same switches are merged into one package
and functionally linked. It is useful for switching two
circuits in-line.
Each switches feature very ow loss, high isolation
l
and wide frequency coverage from 50MHz to 3GHz at
low control voltage of 2.5V.
The ultra small & thin FFP16-C1package is adopted.

DESCRIPTIONS
Common RF port C2. In order to block the DC bias voltage of internal
circuit, an external capacitor is required.
RF port B1. This port is connected with PC1 port by controlling
VCTL2 to -0.2~+0.2V and VCTL1 to 2.5~6.5V. In order to block the
DC bias voltage of internal circuit, an external capacitor is required.
No connected terminal.
Control port 1. The voltage of this port controls PC1 to PA1/PA2 and
PC2 to PB1/PB2 state. The ‘ON’ and ‘OFF’ state is toggled by
controlling voltage of this terminal to high-state (2.5~6.5V) or
low-state (-0.2~+0.2V). The voltage of VCTL2 should be set to
opposite state. The bypass capacitor should be connected with GND
as close as possible for excellent RF performance.
RF port A1. This port is connected with PC1 port by controlling
VCTL2 to -0.2~+0.2V and VCTL1 to 2.5~6.5V. In order to block the
DC bias voltage of internal circuit, an external capacitor is required.

Ground terminal. Please connect this terminal with ground plane as
close as possible for excellent RF performance.
