F2950
High Linearity SP2T Wi-Fi RF Switch
100MHz to 8GHz
F2950
Datasheet
Description
The F2950 is a high power, reflective 5, single-pole double-
throw (SP2T) RF switch. This device covers a 100MHz to 8GHz
frequency range to support a wide variety of applications including
WLAN 802.11.
The F2950 uses a single positive supply voltage and is
compatible with both 1.8V and 3.3V control logic.
Competitive Advantage
The F2950 provides extremely low insertion loss across a very
broad bandwidth while providing high linearity performance
across its operating range.
Optimized for Wi-Fi applications
Wide bandwidth
Low insertion loss
Excellent linearity
High power handling for large peak-to-average applications
Fast switching
No external matching required
Minimal footprint

RFC
RF common port. Matched to 50in the insertion loss state only. If this pin is not 0V DC, then an external
coupling capacitor must be used.
3 VCC Power supply. Bypass to GND with capacitors as close as possible to the pin.
4
RF2
RF2 port. Matched to 50Ω in the insertion loss state only. If this pin is not 0V DC, then an external coupling
capacitor must be used.
5 GND Ground. Ground this pin as close to the device as possible.
6
RF1
RF1 port. Matched to 50Ω in the insertion loss state only. If this pin is not 0V DC, then an external coupling
capacitor must be used.
Exposed pad. Internally connected to GND. Solder this exposed pad to a PCB pad that uses multiple
EP 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.
