GENERAL DESCRIPTION
nPACKAGE OUTLINE
NJG1512V is a GaAs SPDT switch IC featuring high
isolation and low insertion loss.
This switch allows low operating voltage from 2.5V at
the wide frequency range from 1MHz to 3GHz.
NJG1512V is suitable to switch the synthesizer
signals between transmit and receiving circuit.
A very small SSOP package is adopted.

PRECAUTIONS
[1] The external capacitors should be connected to the input and output RF terminals
(P1, P2, PC) to block DC current. Please use a 0.01uF capacitor at 50 to 100MHz, a
0.1uF capacitor at 100 to 500MHz, and 56pF at 500MHz to 2.0GHz.
[2] To avoid coupling between terminals, the capacitors have to be placed at the control
terminals (VCTR1, VCTR2) as close as possible. The capacitor values of 0.01uF at 50 to
100MHz, 100pF at 100 to 500MHz, and 10pF at 500MHz to 2GHz are desired. In
general, the switching time is depend on the capacitor values, so please be careful
choosing capacitor values.
[3] For good isolation characteristics, the ground terminals (2, 3, 5, 6, 9~13 pin) should
be directly connected to the ground patterns and through-holes as close as possible
using relatively wide patterns.

[1]Please connect the bypass capacitor to the power supply terminal of the C-MOS inverter.
[2]In order to stabilize the input impedance of inverter, the input terminal of the C-MOS
inverter should be pulled down by the resistor of 510KW to the ground plane.
