NJG1617K11 DPDT SWITCH GaAs MMIC

NJG1617K11
DPDT SWITCH GaAs MMIC
Q GENERAL DESCRIPTION
The NJG1617K11 is a DPDT switch MMIC which features
low insertion loss, high isolation, wide frequency range
(0.1-over 6GHz) and low operating voltage from 2.7V.
Thin switch is suited for wireless LAN IEEE 802.11b/802.11g
(2.4GHz band) and IEEE 802.11a (5GHz band).
The industrial standard QFN12-11 package is applied.

PRECAUTIONS
[1]The DC blocking capacitors have to be placed at RF terminal of RX, TX, ANT1 and ANT2.
[2] Please locate bypass capacitors (C5,C6) close to appropriate terminals to reduce stripline
influence on RF characteristics.
[3]For good RF performance, the GND terminal must be placed close to ground plane of substrate,
and through holes for GND should be placed near by the GND pin connection.
[4]Exposed pad in the bottom must be connected to ground by via holes.
