ESA MLO Project Extension: Pioneering Push-Push Configuration

In collaboration with the European Space Agency (ESA), SpaceForest has embarked on an exciting new phase of the Master Local Oscillator (MLO) initiative. Building on the success of the completed project “Development and Qualification of Dual Redundant Medium Power Master Signal Source”, we are now entering an 8-month ESA Master Local Oscillator project extension to explore groundbreaking design possibilities.
Proven Success of the Original Project
The initial MLO project resulted in an Engineering Qualified Model with exceptionally low phase noise, meeting the stringent requirements of space applications. The device proved capable of stable performance in a simulated operational environment, making it a strong candidate for integration into high-throughput telecommunication satellites.

Innovation Through Push-Push Configuration
During the project’s simulation phase, our engineers identified a promising approach: a push-push configuration for the MLO. This method offers the potential for a further reduction in phase noise, a critical factor for satellite communication systems requiring ultra-stable frequency references.
The ESA Master Local Oscillator project extension will focus on validating this configuration with space-qualified packaged transistors, ensuring both technological feasibility and compliance with ECSS standards.
Impact on Satellite Technology
If successful, the new configuration could significantly enhance performance for satellites that require centralized, ultra-low phase noise local oscillators feeding multiple frequency converters. This improvement could reduce the number of oscillators onboard, leading to lighter payloads and lower power consumption.
