“…Another approach is to use the 180 • phase shifting technique between the two sub-oscillators to force them into differential oscillation [10,11]. Furthermore, the balanced transmission line such as slotline is suitable for the differential oscillator designs [14][15][16] because it inherently possesses features of equal amplitude and frequency-independent out-of-phase between the two strips. However, in the above reference oscillators, the combination circuits at the common output port are always required at the output [17], which can greatly boost the circuit size, introduce extra loss to the desired signals, and limit the operation bandwidth of the differential oscillators.…”

“…However, in the above reference oscillators, the combination circuits at the common output port are always required at the output [17], which can greatly boost the circuit size, introduce extra loss to the desired signals, and limit the operation bandwidth of the differential oscillators. In [15] and [16], the active devices are placed on one side of the substrate, while the slotline resonator is on the opposite side. Therefore, a transition between the microtrip and slot lines is inevitably needed for power combining.…”

In this paper, a differential oscillator using parallel-strip line (PSL) with an inserted ground plane is proposed. Its two identical sub-oscillators on the opposite sides of a dielectric substrate, sharing a common PSL resonator and common ground plane in the middle of the substrate, generate anti-phase fundamental signals and inphase second harmonics. At the common PSL output, the second harmonics are inherently cancelled out while the fundamental signals are well combined. The combination circuits, as required by the conventional differential circuits, are no longer needed. To further 2220 Chen et al.enhance the suppression of the second harmonics, the inset length of the ground plane into the PSL resonator is optimized to make the second harmonics be suppressed inside each sub-oscillator.

A topology is proposed for designing a low-cost microwave oscillator. This new feedback oscillator makes use of a substrate integrated waveguide (SIW) cavity that acts as a frequency selector as well as a feedback-coupling device. The oscillator is stabilized by using an injection-locking scheme. A 12.02-GHz oscillator prototype was designed. Experimental results for phase noise, locking range, and quality factor of the new circuit are presented. An external of 178 was measured.Index Terms-Cavity, feedback oscillator, phase noise, substrate integrated waveguide (SIW).
