Comparing Linearity Measurements in a GaN Ka-Band Satcom Power Amplifier

The superior power density and power efficiency of GaN-based amplifiers make them ideal for the manufacturing of smaller and more efficient transmitters. There’s only one issue: the non-linear behavior on maximum power areas can degrade the transmitted signal to a point where it becomes useless.

Adjacent Channel Power Ratio (ACPR) measurements can help. Learn more about using this method to establish amplifier behavior under a specific modulated input signal to achieve a clear indication of amplifier performance for a given application.

Accurate Noise Figure Measurement in ERZIA K/Ka-Band Low Noise Amplifiers for Satcom Applications

The satellite communications industry is in constant evolution, always looking for new technologies and approaches to handle the exponentially increasing traffic demand. Driven by this continuous objective, higher RF and Microwave frequency bands have been gradually introduced, initially for networks in relatively low frequencies, such as L-Band, C-Band or X-Band, then for higher frequencies like Ku-Band which is widely used nowadays. The higher the frequency, the wider the channels, so bigger data capacity is required, thus the interest in exploiting the K/Ka-Bands and Q/V Bands.

How to Design RF Amplifiers for Space-based Acousto-optic Tunable Filter Systems

Designing and building an RF amplifier that can boost a low power generated RF signal required by an AOTF crystal that acts as an optical fiber may appear to be easy for experienced RF designers. However, the special conditions required for space-based scientific instruments make this task an interesting challenge.
