Description



The RFASWB438ATF09 is a SOI (Silicon On Insulator) double pole double throw (DPDT) switch with an integrated General

Purpose Input Output (GPIO) control. The RFASWB438ATF09 maintains low insertion and high isolation, which makes it an

ideal choice for Multi-Mode, GSM, EDGE, UMTS, and TLE handset applications.



The RFASWB438ATF09 is ideally suited for applications where high linearity, high isolation, low insertion loss, low current

consumption, and small size are required.



No blocking capacitor requirement on the RF paths ad long as no DC voltage is applied. The RFASWB438ATF09 is

Application



Multi-mode 3G/4G, LTE TRx system.
