The FM1033 is a CMOS, high isolation, Silicon-OnInsulator (SOI) three-pole, three -throw (3P3T) switch. The switch provides high linearity performance, low insertion loss and high isolation.

The FM1033 is compatible with MIPI control, which is a key requirement for many cellular transceivers. RF1, RF3, RF5 pins connect to one of the three other RF port pins (RF2 or RF4 or RF6) 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 FM1033 high isolation 3P3T switch is provided in a QFN (16-pin, 2.0 x 2.0 x 0.55 mm) 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.
