DLI’s Cavity Resonators provide an ideal solution for high performance, low-cost microwave, or millimeter wave oscillators. The patented high-Q cavity resonator devices are fully shielded and designed on our temperature stable, high dielectric constant ceramics.
An equivalent circuit modeling tool was developed that enables optimization of resonator based oscillator designs and constrains circuit element values to realizable combinations. Below are example models at 8 GHz. Two models are shown using CF ceramic, one using FS, and one using CG.
Frequencies of resonator designs range from <1.0 to >67 GHz and can be customized for either solder-surface mount or chip and wire applications. High reliability thin film gold metallization is employed and frequency tolerances as low as 0.1% are attainable.
Applications
Systems: Circuits
Automotive: Microwave & Millimeter-Wave Oscillators
Radar: Fundamental Fixed Frequency Oscillators-Ultra-lo
w Phase Noise (former solution: expensive DRO's and multiplied-up crystal or SAW based device with decreased performance)
Communications: Narrow-Band Tunable VCO or Phase Locked Oscillators (typically ± 3% tuning)(former solution: varactor tuned expensive DRO)
Military: Integration of high performance Oscillators directly on the system motherboard without the expense and complexity of sub assemblies, housing and labor intensive operations typical of former solutions.
Instrumentation: Narrow bandwidth low loss filters (former solution: low loss SAW devices with frequency limitation and poor performance)
