F2914NBGK Datasheet, PDF (1/1 Pages) Integrated Device Technology – High Reliability SP4T RF Switch

High Reliability SP4T RF Switch
GENERAL DESCRIPTION
The F2914 is a high reliability, low insertion loss, 50 Ω
SP4T absorptive RF switch designed for a multitude of
wireless and other RF applications. This device covers
a broad frequency range from 400 MHz to 8000 MHz.
In addition to providing low insertion loss, the F2914
also delivers excellent linearity and isolation
performance while providing a 50 Ω termination to the
unused RF 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.
COMPETITIVE ADVANTAGE
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.
