NJG1660HA8
SPDT SWITCH GaAs MMIC
I GENERAL DESCRIPTION
The NJG1660HA8 is a GaAs SPDT switch IC suited for antenna
switch of WiMAX application and other wireless handsets.
The NJG1660HA8 features high power handling, low insertion loss,
high isolation and wide frequency coverage up to 8.0GHz.
The NJG1660HA8 has ESD protection circuit for good ESD
tolerance.
An ultra- small and ultra-thin package of USB6-A8 is adopted.

PRECAUTIONS
PC
[1] The DC blocking capacitors have to be placed at RF terminal of PC, P1and P2.
[2] For good RF performance, the ground terminals must be placed possibly close to ground plane
of substrate, and through holes for GND should be placed near by the pin connection.
[3] Bypass capacitor (C4, C5) should be placed close to terminal of CTL1 and CTL2 to reduce stripline
influence of RF characteristics.
