FEATURES
● Broadband frequency range: 619 to 5925MHzDESCRIPTION
● The FM1022 is a CMOS, Silicon-On-Insulator● GPIO interface (SOI) double-pole, double-throw (DPDT) switch.
● RoHS compliant package The switch provides high linearity performance,
● Compact 1.1mm x 1.5mm x 0.45mm QFN low insertion loss and high isolation. 10-pin package, MSL1
● Switching is controlled by one control voltage
APPLICATIONS
● 2G/3G/4G/5G antenna swapping pin, VCTL. Depending on the logic voltage level applied to this pin, the RF1 and RF2 pins connect to one of the two other RF3 and RF4 pins through a low insertion loss path, while maintaining a high isolation path to the alternate port, ANT. No external DC blocking capacitors 技 are required on the RF path as long as no DC k voltage is applied externally. 科 e● The FM1022 DPDT switch is provided in a QFN 10- pin, 1.1mm x 1.5mm x 0.45mm package. T The functional block diagram and the pin 特 e configuration are shown in Figure 1. Signal pin assignments and functional pin descriptions are 矽Ch源ipSourc providedinTable1.
