Design of an I-band low phase noise oscillator using a new hair-pin resonator

In this article, a new high Q resonator is presented and it is applied to the design of an I‐band oscillator. The measurement of the resonator itself shows that it provides a higher loaded quality factor when compared with the spiral‐resonator. The oscillator is designed to be operated at 10 GHz usi...

Description
Summary:In this article, a new high Q resonator is presented and it is applied to the design of an I‐band oscillator. The measurement of the resonator itself shows that it provides a higher loaded quality factor when compared with the spiral‐resonator. The oscillator is designed to be operated at 10 GHz using the new resonator to confirm the phase noise performance. The measurement results for the new hair‐pin resonator oscillator show the output power of 8.18 dBm and the phase noise of −103.48 dBc/Hz at 100 kHz offset. © 2009 Wiley Periodicals, Inc.
