Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range (2.7 V to 5.5 V).
   • Connect the supply voltage to the Vcc pin and ground to the GND pin.

2. Control Signal:

   • Apply 0 V to the control pin (CTRL) to switch to one state.
   • Apply 5 V to the control pin (CTRL) to switch to the other state.

3. Signal Path:

   • Connect the input signal to the RF1 or RF2 pin, depending on the desired path.
   • The common pin (COM) will connect to either RF1 or RF2 based on the control signal.

4. Handling:

   • Handle the device with care to avoid static damage.
   • Follow standard ESD (Electrostatic Discharge) precautions during handling and installation.

5. Mounting:

   • Solder the device to the PCB using a reflow soldering process or manual soldering with a controlled temperature.
   • Ensure all pins are properly soldered and inspected for shorts or open circuits.

6. Testing:

   • After mounting, test the device for proper operation by measuring the insertion loss and isolation at the specified frequencies.
   • Verify the control signals are correctly switching the states of the switch.
