Microwave Dynamics’ Dual Loop PLO-4200 design incorporates a low noise sc-cut VCXO to be locked to
10MHz to offer the best phase noise performance achievable.
PLO-4200 Phase Locked Dielectric Resonator Oscillator (PLDRO) utilizes state of the art MIC to provide highly
stable, reliable and efficient signal source at microwave frequencies up to 50 GHz. The low profile and rugged
construction provide excellent durability against harsh environmental conditions
PLO-4200 oscillator is designed using FET and Dielectric Resonator at the gate. High gain, low-noise FETs arebiased 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).
PLO-4200 oscillator is buffered by cascaded low-noise driver and power amplifiers for minimum load pulling,maximum isolation and power. FET 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.
PLO-4200 series proprietary phase lock loop uses Surface Mount Technology. The 10 MHz reference frequency
is locked to a low phase noise VCXO and sampled to output frequency. Produced error voltage due to frequency
drift is sensed by a Wein-Bridge Oscillator to provide the necessary sweep voltage to an ultra H-Q tuning varactor
diode for the purpose of compensation and phase locking.
PLO-4200 series is internally voltage regulated to avoid reverse bias. frequency pushing, bias modulationand voltage transients. A phase lock indicator alarm of TTL type is provided as a feature. The PLO-4200
series externally referenced locked and factory tuned to specified frequency.
