Notes:

1. Both RF ports must be held at 0VDC or DC blocked with an external series capacitor.

2. Latch Enable (LE) has an internal 100KΩ resistor to V

3. Place a 10KΩ resistor to GND.

4. The exposed solder pad on the bottom of the package (See Pin Configuration) must

be grounded for proper device operation.
