Description
The RFASWA141ATF09 is a Single-Pole, Double-Throw (SPDT) switch designed for antenna tuning applications that
require very low RON and COFF. The RFASWA141ATF09 provides rugged power handling and simple 1-bit GPIO control. The
EN pin configures an
“all-off state” as well as low power mode. The RFASWA141ATF09 is manufactured in LGA-9 (1.67 x
1.47 x 0.55 mm
3 ) package
The RFASWA141ATF09 features very low DC power consumption.
The RFASWA141ATF09 has ESD protection devices to achieve excellent ESD performances. No DC Blocking capacitors
are required for all RF ports unless DC is biased externally.
