High Isolation SP2T RF Switch F2913 50MHz to 6000MHz Datasheet Description Features Low insertion loss: 0.79dB at 2GHz The F2913 is a high isolation, low insertion loss, 50 SP2T High isolation: absorptive RF switch designed for a multitude of wireless and RF applications. This device covers a broad frequency range of 71dB at 1GHz 50MHz to 6000MHz. In addition to providing low insertion loss, 65dB at 2GHz the F2913 also delivers high linearity and high isolation 58dB at 4GHz performance while providing a 50 termination at all RF ports. High IIP3: +65dBm at 2.6GHz The F2913 uses a single positive supply voltage of +2.7V to Supply voltage: +2.7V to +5.5V +5.5V and supports three states using either +1.8V or +3.3V 1.8V and 3.3V compatible control logic control logic.

If this pin is not 0V DC, then an external coupling capacitor must be used. 8 RFC RF Common Port. If this pin is not 0V DC, then an external coupling capacitor must be used. 13 RF2 RF2 Port. If this pin is not 0V DC, then an external coupling capacitor must be used. 16 C2 Logic control pin. See Table 7 for proper logic setting. 17 C1 Logic control pin. See Table 7 for proper logic setting. 20 V Power supply. Bypass to GND with capacitors shown in the Figure 30 as close as possible to the pin. DD Exposed Pad. This is internally connected to GND. Solder this exposed pad to a PCB pad that uses EP multiple ground vias to provide heat transfer out of the device into the PCB ground planes. These multiple ground vias are also required to achieve the specified RF performance. 2019 Integrated Device Technology, Inc. 2 January 31, 2019
