Transistor Collector
Transistor Emitter
Anode of the Biasing Diode that matches the thermal and process char-
acteristics of the power transistor. Requires a high-RF-impedance, low-
DC-impedance (e.g., inductor) connection to the transistor base (Pin 4).
Current through the biasing diode (into Pin 3) is proportional to 1/15 the
collector current in the transistor.
