75Ω SP2T RF Switch
5MHz to 3000MHz
The F2971 is a high reliability, low insertion loss, 75Ω absorptive
SP2T RF switch designed for a multitude of cable systems and RF
applications. This device covers a broad frequency range from
5MHz to 3000MHz. In addition to providing low insertion loss, the
F2971 also delivers excellent linearity and isolation performance
while providing a 75Ω termination for the unselected port.
The F2971 uses a single positive supply voltage and supports 3.3V
The F2971 provides broadband RF performance to support the
CATV market along with high power handling and high isolation.
