Power ON / OFF Sequence
Range is set Per the data sheet
Level is set Per the data sheet
RX is Low during TX
RX is Low during TX
Apply Vcc to pins 4,
10, and 11
For Transmit: apply
3.1v to pin-6
RF signal ON time is
0.5uS max. Set RF
input to required level.
Both controls must be
OFF during transmit.
The order is not critical.
Apply a max of 0.4v to
pins 15 and 16

Note1: RF Signal for each specific mode is applied after the DC bias is applied
Note2: Total ON/OFF time includes from 10% of control switching to 90% of RF power
Note3: Listed values on diagram are typical. The maximum is 0.5us for each mode
