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 2MΩ to internal positive supply voltage.
3. Place a 10KΩ resistor in series, as close to pin as possible to avoid freq. resonance.
4. Refer to Power-up Control Settings.
5. The exposed solder pad on the bottom of the package (See Pin configuration) must be
grounded for proper device operation.
6. This pin has an internal 200 k
Ω resistor to ground.
7. Ground must be less than 80 mil (0.08”) from pin 12 proper device operation.
8. When VDD<=3.6V this pin may be connected directly to VDD, when 3.6V< VDD <=5.2V
need to use a voltage divider to reduce voltage on this pin to a voltage in the range +1.17
to 3.6V. See Application note AN-70-006.
9. Place a shunt 10k
Ω resistor to ground.
