RFCM4363
Current Adjustment Using Resistor R5
The RFCM4363 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 221mA and 252mA (typ.).
Within the range of current between 221mA and 252mA gain (S21) change is less than 0.4dB and noise figure change is less than 0.1dB.
