High Reliability SP5T RF Switch
GENERAL DESCRIPTION
The F2915 is a high reliability, low insertion loss, 50 Ω
SP5T absorptive RF switch designed for a multitude of
RF applications including wireless communications.
This device covers a broad frequency range from 400
MHz to 8000 MHz. In addition to providing low
insertion loss, the F2915 also delivers excellent
linearity and isolation performance while providing a
50 Ω termination to the unused RF input ports. The
F2915 also includes a patent pending constant
impedance (KZ) feature. KZ 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 F2915 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 F2915 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.

TYPICAL OPERATING CONDITIONS (TOC)
Unless otherwise noted for the TOC graphs on the following pages, the following conditions apply.
• VDD = 3.3 V.
• TCASE = +25 ºC (TCASE = Temperature of exposed paddle).
• FRF = 2000 MHz.
• RFX is the driven RF port and RFC is the output port.
• Pin = 10 dBm for all small signal tests.
• Pin = +15 dBm/tone applied to selected RFX port for two tone linearity tests.
• Two tone frequency spacing = 5 MHz.
• ZS = ZL = 50 ohms.
• All unused RF ports terminated into 50 ohms.
• For Insertion Loss and Isolation plots, RF trace and connector losses are de-embedded (see
EVKIT Board and Connector loss plot).
• Plots for Isolation and Insertion Loss over temperature and voltage are for a typical path. For
performance of a specific path, refer to the online S-Parameter file.
