The F2934 is a high reliability, low insertion loss, 50Ω
SP2T absorptive RF switch designed for a multitude
of wireless and other RF applications. This device
covers a broad frequency range from 50MHz to
6000MHz. In addition to providing low insertion loss,
the F2934 delivers high linearity and high isolation
performance while providing a 50Ω termination to the
unused RF input ports.
The F2934 uses a single positive supply voltage of
2.7V to 5.25V supporting three states using either
3.3V or 1.8V control logic.
Competitive Advantage
The F2934 provides the following advantages:
■
