Description



The RMASMP491ATF03 is a Single Pole, Fourteen Throw (SP14T) antenna switch with an integrated Mobile Industry

Processor Interface (MIPI) controller. Using an advanced switching technology, the RMASMP491ATF03 maintains

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

applications.



The design integrated two GSM transmit ports and twelve low loss TRX ports. The switch also has an excellent 2

Order Intermodulation 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 is applied. The RMASMP491ATF03 is

manufactured in a compact, 2.5 x 2.9 x 0.78 mm



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)
