Low = 0V to 0.2V. Timing Diagram Level is set Per the data sheet BT is Low during TX and RX VCC PA_EN C_RX C_BT 0.2uSec Time TX RF Signal Transmit Timing Diagram Power ON / OFF Sequence RX is Low during TX 0.2uSec 0.2uSec 0.2uSec BT must be “LOW” during TX and RX modes. Apply a max of 0.4 to pin-13. Apply Vcc to pins 3,4, and 10 Both controls must be OFF during transmit. The order is not critical. Apply a max of 0.4v to pins 9, and 14 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. |
