Description
The RFASWMT2628ATF09 is a CMOS SOI (Silicon On Insulator) Single Pole, Triple Throw (SP3T) switch that operating at
0.5-2.7 GHz. The RFASWMT2628ATF09 is manufactured in a LGA (1.1x1.1x0.55mm
3
) package.
The RFASWMT2628ATF09 features very high isolation with very low DC power consumption.
The RFASWMT2628ATF09 has ESD protection devices to achieve excellent ESD performances. No DC Blocking capacitors
are required for all RF ports unless DC is biased externally
Application
Multi-mode 2G/3G, LTE application receive system.
