F2910
Datasheet
Description
The F2910 is a high reliability, low insertion loss, 50 Ω absorptive
SPST RF switch designed for a multitude of wireless and RF
applications. This device covers a broad frequency range from
30 MHz to 8000 MHz. In addition to providing low insertion loss,
the F2910 also delivers excellent linearity and isolation
performance while providing a 50 Ω termination on RF2 in the
isolation mode. The F2910 includes a patent pending constant
impedance K|Z| feature for the RF2 port. K|Z| maintains near
constant impedance when switching RF ports and improves hot
switching ruggedness. K|Z| minimizes VSWR transients and
reduces phase and amplitude variations when switching.
The F2910 uses a single positive supply voltage supporting either
3.3 V or 1.8 V control logic.
Competitive Advantage
The F2910 provides constant impedance for one RF port during
transitions, improving a system’s hot-switching ruggedness. The
device also supports high power handling and high isolation.
