GENERAL DESCRIPTION

n

PACKAGE OUTLINE

NJG1524PC1 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 low loss, high isolation and
wide frequency coverage from 50MHz to 3GHz at low
control voltage of 2.5V.

The ultra small & thin FFP16-C1package is adopted.

TERMINAL INFORMATION

No. SYMBOL DESCRIPTIONS

1 PA2

RF port A2. This port is connected with PC1 port by controlling

VCTL (L)

to

-0.2~+0.2V and

VCTL(H)

to 2.5~6.5V. In order to block the DC bias voltage

of internal circuit, an external capacitor is required.

2 V

CTL1

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 V

CTL2

should be set to opposite state. The
bypass capacitor should be connected with GND as close as possible
for excellent RF performance.

3 V

CTL2

Control port 2. 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 V

CTL1

should be set to opposite state. The
bypass capacitor should be connected with GND as close as possible
for excellent RF performance.

4 PB2

RF port B2. This port is connected with PC2 port by controlling V

CTL1

to

–0.2~+0.2V and V

CTL2

to 2.5~6.5V. In order to block the DC bias voltage

of internal circuit, an external capacitor is required.

7 PC2

Common RF port C2. In order to block the DC bias voltage of internal
circuit, an external capacitor is required.

9 PB1

RF port B1. This port is connected with PC1 port by controlling V

CTL2

to

–0.2~+0.2V and V

CTL1

to 2.5~6.5V. In order to block the DC bias voltage

of internal circuit, an external capacitor is required.

10 NC No connected terminal.

11 V

GND

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