Abstract
The circuit employs two bipolar transistors, five resistors and a capacitor and can be primarily utilized as a broadband pre-amplifier and also as an oscillator or a mixer. A first transistor is connected to the circuit input and ground. A second transistor is connected to the collector of the first transistor and the supply voltage. One circuit output is connected to the second transistor. Another circuit output is connected to the first transistor via a resistor. The emitter of the first transistor is connected to the second transistor via a second resistor. A third resistor is connected between the base and collector of the first transistor. A fourth resistor is connected between the base and collector of the second transistor.
