The FM1024 V1.0 is a CMOS, high isolation, Silicon-OnInsulator (SOI) dual-pole, four -throw (DP4T) switch. The switch provides high linearity, low insertion loss and high isolation performances.

    The FM1024 V1.0 is compatible with MIPI RFFE V2.1 interface, which is a key requirement for many cellular transceivers. RFOUT1, RFOUT2 pins are connected to one of the four other RFIN port pins (RFIN1/RFIN2/RFIN3/RFIN4) through a low insertion loss path, while maintaining a very high isolation path to the other ports. No external DC blocking capacitors are required on the RF path as long as no DC voltage is applied externally.

    The FM1024 V1.0 is provided in a QFN (16-pin, 2.0 x 2.0) package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 1, too. Signal pin assignments and functional pin descriptions are provided in Table 1
