Constant Impedance K|Z| SPST RF
Switch 30 MHz to 8000 MHz
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.

Electrical Characteristics
Table 4. Electrical Characteristics
Typical Application Circuit: VDD = 3.3 V, TCASE = +25 °C, FRF = 2 GHz, Driven Port = RF2, Input power = 0 dBm, ZS = ZL = 50 E. PCB board
trace and connector losses are de-embedded unless otherwise noted. IIP2 / IIP3: PIN = 13 dBm / tone, 50 MHz spacing. Performance
beyond 5 GHz based on application circuit (Figure 20) using best RF PCB design practices. See note c for details.

a. Items in min/max columns in bold italics are Guaranteed by Test.
b. Items in min/max columns that are not bold/italics are Guaranteed by Design Characterization.
c. To achieve performance beyond 5 GHz, the use of bypass capacitors (BOM C2, C3, and C5) installed close to the device as
embodied in the evaluation board per the application circuit (Figure 20) is required. See the appropriate Typical Operating
Conditions graphs.
