Rakon releases Hi-Rel Space Master Reference Oscillator equipment with 100ppb stability over 20 years.

The Hi-Rel Space MRO (Master Reference Oscillator) equipment is specially designed for GEO telecommunication satellites where precision, frequency stability and ultra-low phase noise are crucial. It achieves a long-term frequency stability down to ±100 ppb over the 20 years of lifetime. Output frequencies are available from 5 to 200 MHz and the MRO can easily be connected to a Master Local Oscillator to create a Frequency Generation Unit. The output level can be adjusted per port.

The equipment is based on 3:1 redundancy architecture, single point failure free and offers 99.99% reliability.

The current baseline includes an integrated DC/DC converter which allows the clock to be powered directly from the primary satellite bus, an ON & OFF TM/TC and one block of 8 outputs @ 10 or 100 MHz. Custom solutions are available on request, including synchronisation to a 1PPS signal, different stability class oscillators, digital electronic frequency control, or additional outputs.

Key features:

• Output frequency: 5 to 200 MHz
• Power bus: 28 to 110 V
• Typical phase noise @100 MHz:
    -105 dBc/Hz (@10 Hz)
    -125 dBc/Hz (@100 Hz)
    -145 dBc/Hz (@1 kHz)
    -155 dBc/Hz (@10 kHz)
• Overall frequency stability: ±100 ppb for 20 years
• 3:1 redundancy
• Reliability: 99.99%

Baseline:
