GENERAL DESCRIPTION

n

PACKAGE OUTLINE

NJG1518KB2 is a SPDT switch IC featured low insertion
loss, medium handling power and high isolation. This device
is suitable for switching of Tx/Rx signals at sub-microwave
applications.

This switch exhibits wide frequency range from 50MHz to

3.0GHz at low operating voltage of 2.5V, and is operated up
to 25dBm at 3.0V operating voltage.

The ultra small & ultra thin FLP6 package is applied.

TERMINAL INFORMATION

No. SYMBOL EXPLANATION

1 P1

RF port. This port is connected with PC port by controlling 6th pin (V

CTL (H)

)

to 2.5~6.5V and 4th pin(V

CTL (L)

) to -0.2~+0.2V. An external capacitor is

required to block the DC bias voltage of internal circuit. (50~100MHz:

0.01uF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF)

2 EXTCAP

External capacitor terminal. The isolation characteristics depends on the
value of the capacitor which connected with GND. An external capacitor is
required to block the DC bias voltage of internal circuit. (50MHz~1.7GHz:
10pF, 1.7~2.5GHz: 5pF)

3 P2

RF port. This port is connected with PC port by controlling 4th pin (V

CTL (H)

)

to 2.5 – 6.5V and 6th pin(V

CTL (L)

) to -0.2~+0.2V. In order to block the DC
bias voltage of internal circuit, an external capacitor is required.
(50~100MHz: 0.01uF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF)

4 V

CTL2

Control port 2. The voltage of this port controls PC to P2 state. The ‘ON’
and ‘OFF’ state is toggled by controlling voltage of this terminal such as
high-state (2.5~6.5V) or low-state (-0.2~+0.2V). The voltage of 6th pin
have to be set to opposite state. The bypass capacitor has to be chosen
to reduce switching time delay from 10pF~1000pF range.

5 PC

Common RF port. In order to block the DC bias voltage of internal circuit,
an external capacitor is required. (50~100MHz: 0.01uF, 0.1~0.5GHz:
1000pF, 0.5~2.5GHz: 56pF)

6 V

CTL1

Control port 1. The voltage of this port controls PC to P2 state. The ‘ON’
and ‘OFF’ state is toggled by controlling voltage of this terminal such as
high-state (2.5~6.5V) or low-state (-0.2~+0.2V). The voltage of 4th pin
have to be set to opposite state. The bypass capacitor has to be chosen
to reduce switching time delay from 10pF~1000pF range.
