Amplifiers for SATCOM all have one thing in common: They all must overcome the free space path loss that satellites have by being great distances from earth. Overcoming that path loss, is not easy to do. Amplifiers have to have enough gain without SNR degradation. Noise figure measurements are a fast way to check on an amplifiers health. Electro Rent has solutions utilizing both VNAs and Signal Analyzers to make noise figure measurements.

S-Band, X-Band, UHF and VHF communication links for SATCOM all have some common features in their design. All use local oscillators and mixing to produce their final output frequencies. Paying attention to phase noise is critical in establishing high-bandwidth, low-noise circuits. Selection of test equipment for phase noise measurement can be challenging. Electro Rent has analyzers and software to cover all bands from VHF to X-Band.

Synthetic Aperture Radar (SAR), which constructs two- or three-dimensional images of a landscape or an object, are highly regarded for their ability to “see” through cloud cover, inclement weather, and at night. SARs are used in surveillance, search and rescue, mapping, tracking and more. Until recently, one downside to SARs was the difficulty in deploying them on small satellites. But with modern, micro-electronic components, small satellite constellations can now take full advantage of SAR imaging.
