INTRODUCTION TO DROs INTRODUCTION TO DROs Dielectric Resonator Oscillators (DROs) are microwave oscillators that use a dielectric resonator (DR) as the frequency stabilizing element in order to achieve excellent frequency stability, high Q and very low microphonics. The DR, when used as part of the resonating circuit of any active microwave device, produces a steady state oscillation under the right conditions at the resonant frequency of the DR. DIELECTRIC RESONATOR MAGNETICALLY COUPLED TO DIFFERENT PORTS OF TRANSISTOR USING TRANSMISSION LINE MAGNETIC FIELD DR O/P MATCH OSCILLATOR THEORY AND CIRCUIT DESIGN MITEQ’s DRO circuits utilize both silicon bipolar transistors and GaAs MESFET devices. All microwave oscillators are designed by adding resonating elements (L, C or R) in various configurations to different ports of a transistor. These elements generate a negative resistance at a certain resonant frequency and set the device into oscillation. In the case of a DRO, the resonating element is the DR, which can be modeled electrically as an L, C, R network, as shown in Figure 1.

This material exhibits a high Q (9000 @ 10 GHz) and low temperature coefficient of frequency (TC to ±6 ppm/°C typical). The cylindrical shape as shown in Figure 1 is the most popular. It has good separation between the desired TEδ(0,1) mode and other higher order resonant modes, making it easier to couple to microstrip circuits, as well as easy to mount. The resonator is magnetically coupled to one or more ports of the transistor using a transmission line, as shown in Figure 2. 1 L1 R1 C1 2 OSCILLATOR FABRICATION TECHNIQUES MITEQ DROs are manufactured using state-of-the-art thin-film hybrid micro-circuit technology. These DROs are suited for applications requiring rugged construction for operation under severe environmental stress. TYPICAL DRO PERFORMANCE SPECIFICATIONS AND APPLICATIONS When comparing different types of oscillators versus a DRO, an engineer may wish to consider the following performance specifications: FREQUENCY ACCURACY AND SETTABILITY The frequency accuracy of a free-running DRO is typically within 500 kHz and can be set to within 100 kHz. FREQUENCY STABILITY ‘ DROs are highly stable free-running oscillators exhibiting low temperature coefficient of frequency drift (typically 4 ppm/°C) and have better stability than free-running cavity oscillators, Gunn diode oscillators or VCOs. 47
