POWER DOUBLER MODULE
Current Adjustment Using Resistor R5
The RFCM3050 can be operated over a wide range of current to provide maximum required performance with minimum current consumption.
Changing the value of resistor R5 on application circuit allows a variation of the current between 420mA and 345mA (typ.). Within the range of
current between 420mA and 345mA gain (S21) change is less than 0.4dB and noise figure change is less than 0.1dB.
