Description



The RFASWR681CTF03 is a dual Single Pole, Six Throw (2xSP6T) antenna switch with an integrated Mobile Industry

Processor Interface (MIPI) controller. Using an advanced switching technology, the RFASWR681CTF03 maintains

low insertion and high isolation, which makes it an ideal choice for UMTS, CDMA2000, EDGE, GSM, and LTE

applications.



Distortion (IMD2/IMD3) performance.



Switching is controlled by the MIPI decoder and High ESD tolerance of 2kV HBM at all pins.



No blocking capacitor requirements on the RF paths as long as no DC voltage are applied. The RFASWR681CTF03



The functional block diagram is shown in Figure 1. The pin assignment and package are shown in Figure 2. Signal

pin assignments and functional pin descriptions are provided in Table 1.

Application



2G/3G/4G multimode cellular handsets (LTE, UMTS, CDMA2000, EDGE, GSM, TDD-LTE, TD-SCDMA)

：



Carrier aggregation diversity
