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 VDD.
3. Place a shunt 10KΩ resistor to GND.
4. The exposed solder pad on the bottom of the package (See Pin Conï¬guration) must
be grounded for proper device operation.
