NJG1663K44
X-SP4T SWITCH GaAs MMIC
GENERAL DESCRIPTION
The NJG1663K44 is a X (Cross) -SP4T* switch GaAs MMIC, which is
suitable for switching of balanced bandpass filters. The NJG1663K44
features very low phase error between on-state paths, low insertion loss,
low control voltage and wide frequency coverage. The ESD protection
circuits are integrated in the IC to achieve high ESD tolerance. The very small
and very thin QFN16-44 package is adopted.
PACKAGE OUTLINE

PRECAUTIONS
[1]
The DC blocking capacitors (C1~C10) have to be placed at RF terminal of PCA, PCB, P1A, P2A, P3A, P4A, P1B,
P2B, P3B, and P4B.
[2]
To reduce strip line influence on RF characteristics, please locate bypass capacitor (C11) close to VDD terminal.
[3]
For good isolation, the GND terminal must be connected to the ground plane of substrate, and through-holes for
GND should be placed near by the pin connection.
