RFPD2930

Current Adjustment Using Hybrid Pin 4

The RFPD2930 can be operated over a wide range of current to provide maximum required performance with minimum current

consumption. A single external resistor connected between pin 4 and GND allows variation of current between 430mA and 220mA

(typ.). Within the recommended range of current between 430mA and 370mA gain (S21) change is less than 0.2dB and noise

figure change is less than 0.1dB. If pin 4 is not connected the devices operates at maximum current, see table below.
