NJG1642HE3
X SPDT SWITCH GaAs MMIC
! GENERAL DESCRIPTION
The NJG1642HE3 is a GaAs X (Cross) SPDT switch MMIC. This
is suitable for the application of selecting one circuit with two ports
such as balanced type circuit from among two circuits with two
ports. This switch features low insertion loss, high isolation, and
wide frequency coverage from 50MHz to 3GHz at low control
voltage of 1.85 V. The ultra-small and ultra-thin USB12 package
is adopted.
! FEATURES
" Low voltage operation
" Low voltage Logic control
" Low insertion loss

[1] The DC blocking capacitors have to be placed at RF terminal of PC1, PC2, PA1, PA2, PB1, PB2.
[2] To reduce stripline influence on RF characteristics, please locate bypass capacitors (C7, C8) close to
each terminal within 3mm.
[3] To avoid degradation of isolation or high power characteristics, please layout ground pattern right
under the IC.
