nGENERAL DESCRIPTION nPACKAGE OUTLINE

NJG1523KB2 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.

RF port. This port is connected with PC port by controlling 6th pin (V
to 2.5~6.5V and 4th pin(V

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

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