High Reliability SP4T RF Switch

D
ESCRIPTION
The F2914 is a high reliability, low insertion loss, 50
SP4T absorptive RF switch designed for a multitude of
RF applications including wireless communications.
This device covers a broad frequency range from
50 MHz to 8000 MHz. In addition to providing low
insertion loss, the F2914 also delivers excellent
linearity and isolation performance while providing a
50 termination to the unused RF input ports. The
F2914 also includes a patent pending constant
impedance (K
Z
) feature. K
Z
improves system hot
switching ruggedness, minimizes LO pulling in VCOs,
and reduces phase and amplitude variations in
distribution networks. It is also ideal for dynamic
switching / selection between two or more amplifiers
while avoiding damage to upstream /downstream
sensitive devices such as PAs and ADCs.
The F2914 uses a single positive supply voltage
supporting three logic control pins using either 3.3 V or
1.8 V control logic. Connecting a negative voltage to
pin 20 disables the internal negative voltage generator
and becomes the negative supply.

DVANTAGE
The F2914 provides constant impedance in all RF ports
during transitions improving a system’s hot-switching
ruggedness. The device also supports high power
handling, and high isolation; particularly important for
DPD receiver use.
