Datasheet
High Reliability SP5T RF Switch
400 MHz to 8000 MHz
GENERAL DESCRIPTION
FEATURES
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.
FUNCTIONAL BLOCK DIAGRAM
RFC
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.

APPLICATIONS INFORMATION
Default Start-up
There are no internal pull-up or pull-down resistors on the Control pins.
Logic Control
Control pins V1, V2, and V3 are used to set the state of the SP5T switch (see Table 1).
External Vss
The F2915 is designed with an on-chip negative voltage generator. This on-chip generator is enabled by
connecting pin 20 of the device to ground. To disable the on-chip generator apply a negative voltage to pin 20
(VSSEXT) of the device within the range stated in the Recommended Operating Conditions Table.
Power Supplies
A common VDD 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.
Control Pin Interface
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 pins
17, 18, and 19 as shown below.

EVKIT OPERATION
External Supply Setup
Set up a VDD power supply in the voltage range of 2.7 V to 5.5 V and disable the power supply output.
If using the on-chip negative voltage generator install a 2-pin shunt to short pins 3 and 4 of J9.
If an external negative voltage supply is to be used set its voltage within the range of -3.6 V to
-3.2 V and disable it. Also, be sure there are no jumper connections on pins 3 and 4 of J9.
Logic Control Setup
Using the EVKIT to manually set the control logic:
On connector J9 connect a 2-pin shunt from pin 7 (VDD) to pin 8 (VDD_CTRL). This connection provides
the VDD voltage supply to the Eval Board logic control pull up network.
On connector J9 connect a 2-pin shunt from pin 9 (LVSEL2) to pin 10 (LVSEL). This connection enables R7
(15 kΩ) and R8 (22 kΩ) to form a voltage divider to set the proper logic control levels to support the full
voltage range of VDD. Note that when using the on-board R7 / R8 voltage divider the current draw from
the VDD supply will be higher by approximately VDD / 37 kΩ.
Connector J9 has 3 logic input pins: V1 (pin 20), V2 (pin 18), and V3 (pin 16). See Table 1 for Logic Truth
Table. With the pullup network enabled (as noted above), when these pins are left open a logic high will
be provided through pull up resistors R4, R5, and R6. To set a logic low to V1, V2, and V3 connect 2-pin
shunts from pin 16 to pin 15, pin 18 to pin 17 and pin 20 to pin 19 respectively.
Using external control logic:
Pins 6, 7, 8, 9, and 10 of J9 should have no connection. External logic controls can be applied to J9 pins
16 (V3), 18 (V2) and 20 (V1). 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 VDD power supply to pin 2 (VDD) and pin 1 (GND) of J9.
If the external negative voltage source is to be used, connect the disabled supply to pin 4 (VSSEXT) and
pin 3 (GND) of J9. If using on-chip negative supply be sure the 2-pin shunt is installed connecting pin 3 to
pin 4.
Enable the VDD supply then enable the VSSEXT supply (if used).
Set the desired logic setting using V1, V2, and V3 to achieve the desired Table 1 setting. Note that
external control logic should not be applied without VDD being applied first.
Turn-off Procedure
If using external control logic V1, V2, V3 must be set to a logic low.
Disable any external VSSEXT supply.
Disable the VDD supply.
