connection
2) Connect common ground terminal to the Ground (GND) pin on the board.
3) Connect terminals VC1 5.0, VC2 5.0, VC3 5.0, VC1 2.4, VC2 2.4 together and apply to positive supply (VC=3.3V).
4) Connect terminals VM 2.4, VM2 5.0 and VM13 5.0 together and connect to positive supply (VM=3.3V).
5) Connect voltmeter to Detector Output, pin DT1 5.0 and to DT1 2.4.
6) Connect logic control pins VL 5.0 and VL 2.4 together and apply 0V.
positive currents flowing into the pins:
Now only the 2.4GHz PA is on.
Observe the following
7) Apply positive voltage of +3.0V to logic control pins VL 5.0 and VL 2.4.
positive currents flowing into the pins:
Now only the 5GHz PA is on.
Observe the following
8) Apply input RF power to SMA connector pin RF IN 2.4 or RF IN 5.0. Currents on collector pins will vary depending on the
input drive level.
Recommended turn-off sequence:
Use reverse order described in the turn-on sequence on the previous page.
