What is SWaP-C?

Size, Weight, Power and Cost.

Multiplied together, they produce a number that limits the possible use cases the higher it is, particularly in application areas where these factors count:

  • When payload is measured to the gram
  • When you don’t have an inch to space
  • When power needs to be conserved
  • When cost is critical

The Spectratime mRO-50 is a breakthrough low SWaP-C Miniaturized Rubidium Oscillator designed to meet the latest commercial, military and aerospace requirements where time stability and power consumption are critical.

It provides a one day holdover below 1µs and a retrace below 1 x 10-10 in a form factor (50.8 x 50.8 x 19.5mm) that takes up only 51 cc of volume (about one-third of the volume compared to standard rubidiums) and consumes only 0.45W of power, or about ten times less than existing solutions with similar capabilities.

The Spectratime mRO-50 Miniaturized Rubidium Oscillator provides accurate frequency and precise time synchronization to mobile applications, such as military radio-pack systems in GNSS denied environments. Its wide-ranging operating temperature of -40°C to +80°C is ideal for applications in extreme environments.
