X-SP4T SWITCH GaAs MMIC

GENERAL DESCRIPTION

PACKAGE OUTLINE

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,

circuits are integrated in the IC to achieve high ESD tolerance.

The very small

and very thin QFN16-44 package is adopted.

*) X-SP4T is a paired SP4T switch controlled synchronously. The X-SP4T includes two

SP4T switches whose RF lines have crossings inside the MMIC.
