Datasheet
High Reliability SP2T RF Switch
50 MHz to 8000 MHz
GENERAL DESCRIPTION
FEATURES
The F2932 is a high reliability, low insertion loss, 50 Ω
SP2T absorptive RF switch designed for a multitude of
wireless and other RF applications. This device covers
a broad frequency range from 50 MHz to 8000 MHz.
In addition to providing low insertion loss, the F2932
also delivers high linearity and high isolation
performance while providing a 50 Ω termination to the
unused RF input port.

•
•
•
The F2932 uses a single positive supply voltage of
2.7 V to 5.5 V supporting three states using either
3.3 V or 1.8 V control logic.
COMPETITIVE ADVANTAGE
High Isolation:
o 70 dB @ 1 GHz
o 67 dB @ 2 GHz
o 65 dB @ 3 GHz

High Linearity:
o IIP2 of 111 dBm
o IIP3 of 64 dBm @ 2 GHz
Wide Single Positive Supply Voltage Range
3.3 V and 1.8 V compatible control logic
Operating temperature -40 °C to +105 °C
4 mm x 4 mm 16 pin QFN package

PIN = +10 dBm for all small signal tests.
PIN = +15 dBm/tone applied to RF1 or RF2 port for two tone linearity tests.
Two tone frequency spacing = 1 MHz.
RF1 or RF2 is the driven RF port and RFC is the output port.
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.

FUNCTION
Power Supply. Bypass to GND with capacitors shown in the
Typical Application Circuit as close as possible to pin.
Controls the selected path when EN is low. Is disabled when EN
is logic high. See Table 1.
RF Common Port. Matched to 50 Ω when one of the 2 RF ports
is selected. If this pin is not 0 V DC, then an external coupling
capacitor must be used.
Ground. Also, internally connected to the ground paddle. Ground
this pin as close to the device as possible.
EN as a logic low allows VCTL to control the selected switch
path. With EN set to logic high puts the part in all paths off state
and disables the control of VCTL. See Table 1.
RF1 Port. Matched to 50 Ω. If this pin is not 0 V DC, then an
external coupling capacitor must be used.
RF2 Port. Matched to 50 Ω. If this pin is not 0 V DC, then an
external coupling capacitor must be used.
Exposed Pad. Internally connected to GND. Solder this exposed
pad to a PCB pad that uses multiple ground vias to provide heat
transfer out of the device and into the PCB ground planes. These
multiple ground vias are also required to achieve the specified
RF performance.

APPLICATIONS INFORMATION
Default Start-up
There are no internal pull-up or pull-down resistors on the VCTL or EN pins.
Logic Control
Control pins VCTL and EN are used to set the state of the SP2T switch (see Table 1).
Power Supplies
A common VCC power supply should be used for all pins requiring DC power. All supply pins should be
bypassed with external capacitors to minimize noise and fast transients. Supply noise can degrade noise figure
and fast transients can trigger ESD clamps and cause them to fail. Supply voltage change or transients should
have a slew rate smaller than 1 V / 20 µs. In addition, all control pins should remain at 0 V (+/- 0.3 V) while
the supply voltage ramps or while it returns to zero.

If control signal integrity is a concern and clean signals cannot be guaranteed due to overshoot, undershoot,
ringing, etc., the following circuit at the input of each control pin is recommended. This applies to control
pin 2 (VCTL) and pin 5 (EN) as shown below.

EVKIT OPERATION
External Supply Setup
Set up a VCC power supply in the voltage range of 2.7 V to 5.5 V and disable the power supply output.
Logic Control Setup
Using the EVKIT to manually set the control logic:
On connector J6 connect a 2-pin shunt from pin 3 (VCC) to pin 4 (VLOGIC). This connection provides the
VCC voltage supply to the Eval Board logic control pull up network. Resistors R5 and R6 form a voltage
divider to set the Vhigh level over the 2.7 V to 5.5 V VCC range for manual logic control.
Connector J6 has 2 logic input pins: EN (pin 5) and VCTL (pin 7). See Table 1 for Logic Truth Table. With
the pullup network enabled (as noted above) these pins can be left open to provide a logic high through
pull up resistors R3 and R4. To set a logic low for EN and VCTL connect 2-pin shunts on J6 from pin 5
(EN) to pin 6 (GND) and from pin 7 (VCTL) to pin 8 (GND).
Note that when using the on board R5 / R6 voltage divider the current draw from the VCC supply will be
higher by approximately VCC / 33k Ω.
Using external control logic:
Pins 3, 4, 6, and 8 of J6 should have no external connection. External logic controls are applied to J6 pin 5
(EN) and pin 7 (VCTL). See Table 1 for Logic Truth Table.
Turn on Procedure
Setup the supplies and Eval Board as noted in the External Supply Setup and Logic Control Setup
sections above.
Connect the preset disabled VCC power supply to the red VCC loop and ground to GND1 or GND2.
Enable the VCC supply.
Set the desired logic setting using J6 pin 5 (EN) and pin 7 (VCTL) to achieve the desired Table 1 setting.
Note that external control logic should not be applied without VCC being present.
Turn off Procedure
If using external control logic for EN and VCTL then set them to a logic low.
Disable the VCC supply.
