GaAs INTEGRATED CIRCUIT
PG2181T5R
Document No. PG10680EJ01V0DS (1st edition)
Date Published October 2007 NS
DESCRIPTION
The
PG2181T5R is a GaAs MMIC high power DP4T switch which was developed for WiMAX.
This device can operate frequency from 2.3 to 3.8 GHz, having the low insertion loss and high isolation.
This device is housed in a 20-pin plastic RQFN (Rectangle Quad Flat Non-leaded) package. And this package is
able to high-density surface mounting.
