深圳市特美威电子有限公司MRO控制基准振荡器

Spectrum Microwave’s line of Master reference oscillators (MROs) is vibration hardened ultra low noise Crystal oscillators intended for an airborne military application.

特点

● SC cut crystal for stability and low noise.

● Ovenized oscillator has a less than 10-minute warm-up to achieve 0.5 PPM accuracy.

● Integrated doublers (x2 and x4), amplifier, built in power test, and band pass filter circuits.

● TTL oven ready indicator.

● Internal voltage regulation to minimize pushing.

● Low resonance (<10 Hz) vibration isolation system to minimize the effects of vibration on phase noise performance.
