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 100K7 resistor to V_DD.
3. Place a 10K7 resistor in series, as close to pin as possible to avoid freq. resonance.
4. Place a shunt 10K7resistor to GND
5. The exposed solder pad on the bottom of the package (See Pin configuration) must
be grounded for proper device operation.
