How to power the RF transmitter while i have to transmit any command?
After transmit power should be OFF.
Next time when i have to send command power should be ON, Otherwise OFF.
power is given by the battery.
Note : RF chip is connected to the Microcontroller and data is send via SPI?
can anyone help me?
 

Your question isn't very specific.

Most people use an electronic switch (a transistor) to power a module temporarily. Some RF transmitters can be also set to low power idle state and don't need a switch.
