1.6 TO 3 GHz OSCILLATOR.

摘要

A high-frequency oscillator is provided for a frequency range of 1.6 to 3 GHz. An oscillator stage includes an oscillator transistor and a voltage-controlled resonator unit. A buffer stage is connected at an output of the oscillator stage. The resonator unit includes an open resonator in the form of an etched structure with a wavelength which is shorter than lambda/4 (where lambda is an oscillator length). The resonator unit includes a voltage-controlled variable-capacitance diode, and a resonator terminal is connected between the voltage-controlled variable-capacitance diode of the resonator unit and the oscillator transistor of the oscillator stage. The resonator is preferably an open microstrip resonator, and the stages are disposed in a standardized housing in SMD (surface mounted device) technology.
