The SMA540B is a NPN Transistor integrating a current mirror as biasing.
In this way the IC (collector current) can be controlled setting the current at Bias pin according to IC = 10 * IBIAS.
The IBIAS current is easy adjustable using an external resistor.
SMA540B Active Biased RF Transistor PRELIMINARY DATA • HIGH GAIN LOW NOISE AMPLIFIERS Gms = 19 dB at 1.8 GHz • CURRENT EASY ADJUSTABLE BY AN EXTERNAL RESISTOR • OPEN COLLECTOR OUTPUT • TYPICAL SUPPLY VOLTAGE: 1.4-3.
