DRO-1000 series Dielectric Resonator
Oscillator (DRO) utilizes state of the art MIC to provide a highly stable,
reliable and efficient signal source at microwave frequencies up to 40 GHz. The
low profile and rugged construction provide excellent durability against harsh
environmental conditions.
DRO-1000 series oscillator is
designed using GaAs FET or BJT amplifier with series feedback at source and
Dielectric Resonator at the gate. High gain, low-noise GaAs FETs/BJTs are biased
positively or negatively at the gate to ensure minimum phase-noise. The device
is carefully matched for maximum power, minimum phase-noise and Voltage
standing-Ratio (VSWR). The oscillator is matched for maximum temperature
stability and optimum negative resistance.
DRO-1000 series
oscillator is buffered by cascaded low-noise driver and power amplifiers for
minimum load pulling, maximum isolation and power. GaAs FET/BJT devices are
directly attached to gold plated Kovar carriers to minimize shear effect and
maximize heat sinking. Kovar carriers are soldered to the chassis to provide an
efficient thermal junction and a stable structure for reduction of microphonics.
To ensure oscillator stability over the full temperature range, high-Q low
dielectric constant resonators are chosen with proper temperature coefficient to
compensate for frequency drift. Where extreme stability is required, a miniature
heater can be provided to ensure constant temperature and minimum drift.
DRO-1000 series provide several advantages over other microwave signal
sources, such as Gunn Gravity Oscillators and Crystal Multiplier Chains. The
table below offers a brief summary comparison of the other sources.
DRO-1000 series is internally voltage regulated to avoid reverse bias,
frequency pushing, bias modulation and voltage transients. Mechanical frequency
adjustment is provided for desired frequency setting within the bandwidth.
