Low = 0V to 0.2V Timing Diagram Level is set Per the data sheet VCC PA_EN C_RX 0.2uSec Time TX RF Signal Transmit Timing Diagram Power ON / OFF Sequence RX is Low during TX 0.2uSec 0.2uSec 0.2uSec Apply 3.6v to pins 4, 10, and 11 Both controls must be OFF during transmit. The order is not critical. Apply a max of 0.4v to pins 15 and 16 For Transmit: apply 3.1v to pin-6 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 LNA_EN RX is Low during TX RF signal ON time is 0.5uS max. Set RF input to required level. Range is set Per the data sheet |
