Application Board Bias Procedure
Step 1. Connect DC ground.
Step 2. Connect all V_CC and V_REF lines to 3.5 V supply, labeled 2.
Step 3. With the RF off, apply 2.7 V_DC to V_APC1, 2 control pins.
Verify the I_CQ current is approximately 250 mA, labeled 3.
Step 4. Apply RF signal data -30 dBm level and observe that the
output level is approximately 10 dBm or the gain of the
device is approximately 40 dB.

source be adjusted such that 3.5 V is measured at the
board. The high collector currents will drop the collector
voltage significantly if long leads are used. Adjust the bias
voltage to compensate.
