Quantic Microwave Dynamics PLO-5000 Phase Locked Oscillator with an Internal Reference using a Phase Locked Loop (PLL) IC
See full specification tab below or
PLO-5000 Series Phase Locked Dielectric Resonator Oscillator (PLDRO) utilizes state-of-the art MIC and SMT to provide crystal stability at microwave frequencies up to 40 GHz. The low profile and rugged construction provide excellent durability against harsh environmental conditions.
PLO-5000 oscillator is designed using FET or BJT amplifier with series feed back at source and Dielectric Resonator at the gate. High gain, low-noise FETs/BJTs are biased positively or negatively at the gate to ensure minimum phase-noise. The devise is carefully matched for maximam power, minimum phase-noise and Voltage Standing Wave Ratio (VSWR). The oscillator is matched for maximum temperature stability and optimum negative resistance.
PLO-5000 oscillator is buffered by cascaded low-noise driver and power amplifiers for minimum load pulling, maximum isolation and power. FET/BJT devices are directly attached to gold plated Kovar carriers to minimize shear effect and maximize heat sinking. Kovar carriers are mounted 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, the tuning elements are precisely designed and positioned to compensate for temperature drift by a factor of three.
PLO-5000 series uses PLL chip which provides a variety of options. The Reference frequency up to 250 MHz with enhanced frequency resolution; integar-N and fractional-N capability. The oscillator goes up to 20 GHz fundamental frequency; frequencies with 20 to 40 GHz are accomplished with a multiplier and driver amplifier.
PLO-5000 series is internally voltage regulated to avoid reverse bias. frequency pushing, bias modulation and voltage transients. The PLO-5000 series are internally reference locked and factory tuned to specified frequency. Mechanical frequency adjustment is provided for optimum phase voltage setting.
