Abstract:
A dual-band oscillator includes a first oscillation circuit and a second oscillation circuit. A first emitter bias resistor for setting the emitter current of a first oscillation transistor in the first oscillation circuit is provided between the emitter of the first oscillation transistor and a second inductance element in the second oscillation circuit. A second emitter bias resistor for setting the emitter current of a second oscillation circuit in the second oscillation circuit is provided between the emitter of the second oscillation transistor and a first inductance element in the first oscillation circuit.
