Abstract
A dielectric resonator oscillator includes a dielectric resonator; a transmission line disposed adjacent the dielectric resonator; an active device having an input electrically connected to the transmission line; a matching network having an input electrically connected to an output of the active device and an output configured to be connected to a load; wherein both the transmission line and the active device are positioned sufficiently close to the dielectric resonator to form part of a resonant circuit with the dielectric resonator.
Claims22
A circuit for frequency sampling, the circuit comprising:
- a first analog-to-digital converter that receives a first satellite signal, the first analog-to-digital converter configured to create a first digital output signal representing the first satellite signal;
- a second analog-to-digital converter that receives a second satellite signal, the second analog-to-digital converter configured to create a second digital output representing the second satellite signal;
- a dielectric resonator oscillator having an output;
- and
- a clock generator circuit having an input coupled to the oscillator output and configured to output one or more clocks used by the first and second analog-to-digital converters;
- wherein the first and second analog-to-digital converters are in an integrated circuit and a resonator element of the dielectric resonator oscillator is coupled to the integrated circuit.
An oscillator circuit, comprising:
- a dielectric resonator;
- a transmission line disposed adjacent the dielectric resonator;
- an active device having a first terminal electrically connected to the transmission line;
- a matching network having a first terminal coupled to a second terminal of the active device;
