AEM

In every satellite, a highly-sophisticated power distribution system is responsible for managing the flow of energy from solar arrays and batteries to every onboard system. Power must be conditioned, regulated, and distributed to sensitive electronics with flawless precision.

The power distribution system acts as the mission's central power hub, taking the energy that it receives and redistributing it to every component on the satellite. This system includes complex electronics that regulate voltage, condition power to remove noise, and protect circuits from overloads.

Setting the standard in satellite power distribution and protection

AEM's solutions are engineered for endurance, delivering circuit protection and power distribution for mission-critical satellite applications.

Our RF, microwave, and mmWave components are essential for the communication links that define a satellite's mission, and their specific requirements vary across different orbits. LEO, MEO, and GEO constellations all require specific RF components for operational efficiency in differing conditions. Our high-reliability fuses are a core part of power protection systems, providing a critical last line of defense against errors.

  • RF filters are utilized in the transmit and receive paths to ensure that only the desired frequencies are allowed to pass. This is critical for preventing interference in satellite communications.
  • Isolators allow RF signals to pass in only one direction, acting as a critical protection component. If a reflected signal comes back due to a mismatch, the isolator absorbs the signal, preventing it from damaging other sensitive components.
  • Circulators route an RF signal in a circular direction, and are commonly used in duplexing, where a single antenna is used for both transmitting and receiving.
  • Switches are essential for routing signals between different paths or channels. In satellites, they are fundamental for enabling redundancy, allowing the system to switch from a primary antenna to a backup in the event of a failure.
  • High-reliability fuses are a non-negotiable component of any satellite's power system, serving as the final line of defense against catastrophic electrical failure. These fuses are specially engineered for critical fault isolation, robust power management, and survivability in the harsh conditions of space.
