F2932 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.

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. 13 High Reliability SP2T RF Switch F2932 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. Control Pin Interface 13 14 15 16 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. 1 12 50Ω 5k ohm 2 VCTL 11 2pF 3 10 50Ω 4 8 7 6 5 9 5k ohm EN 2pF High Reliability SP2T RF Switch 14 F2932, Rev 1 05/12/2016 F2932 EVKIT PICTURES TOP VIEW BOTTOM VIEW F2932, Rev 1 05/12/2016 15 High Reliability SP2T RF Switch F2932 EVKIT / APPLICATIONS CIRCUIT High Reliability SP2T RF Switch 16 F2932, Rev 1 05/12/2016 F2932 EVKIT BOM Part Reference QTY DESCRIPTION Mfr.

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.
