75Ω SPST RF Switch
1MHz to 3500MHz
F2911
Datasheet
Description
The F2911 is a high reliability, low insertion loss, 75Ω SPST RF
switch designed for a multitude of wireless and RF applications.
This device covers a broad frequency range from 1MHz to
3500MHz. In addition to providing low insertion loss, the F2911
also delivers excellent linearity and isolation performance while
providing a 75Ω termination on one port in the isolation mode.
The F2911 uses a single positive supply voltage supporting either
3.3V or 1.8V control logic.
Competitive Advantage
The F2911 provides broadband RF performance to support the
CATV market along with high power handling, and high isolation.
Low insertion loss
High isolation
Excellent linearity
Extended temperature range

Pin Name
Function
1, 4 NC No internal connection. This pin may be connected to the exposed paddle and can be grounded.
2, 3
GND
Ground. This pin is internally connected to the ground paddle. Ground this pin as close to the device as
possible.
5
RF1
RF1 port. This pin is matched to 75in the insertion loss state only. If this pin is not 0V DC, then an
external coupling capacitor must be used.
6 VDD Power supply. Bypass to GND with capacitors as shown in the Figure 16 as close as possible to pin.
7 V1 Logic control pin. See Table 7 for proper logic setting.
8 RF2 RF2 port. Matched to 75Ω. If this pin is not 0V DC, then an external coupling capacitor must be used.
Exposed pad. This pad 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 and into the PCB ground planes. These
multiple ground vias are also required to achieve the specified RF performance.
