Dual-band oscillator
First Claim
1. A dual-band oscillator comprising:
- a first oscillating transistor for generating an oscillation signal in a first frequency band from a collector thereof;
a first inductor for supplying electric power to the collector of the first oscillating transistor;
a first switching element for switching the first oscillating transistor between an active state and an inactive state;
a second oscillating transistor for generating an oscillation signal in a second frequency band from a collector thereof;
a second inductor for supplying electric power to the collector of the second oscillating transistor;
a second switching element for switching the second oscillating transistor between an active state and an inactive state; and
an output terminal for outputting the oscillation signal in the first frequency band or the oscillation signal in the second frequency band to outside of the dual-band oscillator;
wherein the first switching element is disposed between the first inductor and the output terminal, and the second switching element is disposed between the second inductor and the output terminal.

Abstract
When two oscillation signals are output from a common terminal through switching, to reduce attenuation of the oscillation signals, a dual-band oscillator includes a first oscillating transistor for generating an oscillation signal in a first frequency band; a first inductor for supplying power to a collector of the first oscillating transistor; a first switching element for switching the first oscillating transistor; a second oscillating transistor for generating an oscillation signal in a second frequency band; a second inductor for supplying power to a collector of the second oscillating transistor; a second switching element for switching the second oscillating transistor; and an output terminal for outputting the oscillation signal in the first frequency band or in the second frequency band. The first switching element is disposed between the first inductor and the output terminal, and the second switching element is disposed between the second inductor and the output terminal.
