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.

Advantages of Suspended Substrate Stripline Microwave Filters
Filters are key components in any RF/microwave system. From mobile networks to the most sophisticated military RADAR, every single device needs at some point to select or reject specific frequencies of the RF spectrum. The different technologies to implement this functionality have been evolving along with the RF technology. There are several technologies available nowadays to implement different types of filters. Each one can offer advantages in terms of insertion loss, selectivity, size, fractional bandwidth, power handling, etc.

Wideband High Power Amplifiers (WHPAs) Product Review
Microwave High Power Amplifiers (HPA) are a key component on every RF and microwave system. In this product review we discuss how Wideband High Power Amplifiers (WHPAs) play an important role to boost RF power levels for antennas (or TWTAs) and deliver RF energy.
WHPAs serve the needs of RF system designers who require more power and additional bandwidth while optimizing size and efficiency when high reliability and excellent performance are critical. ERZIA WHPAs are well suited for 5G and 6E, electronic warfare, satellite communications, aviation connectivity, and other applications that require higher bandwidths, higher frequencies, higher power levels, and robust, reliable hardware.
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.
Two key elements are critical for the overall performance of the instrument: the acousto-optic tuneable filter (AOTF) and its associated radio frequency driver. Read the tech brief to learn more:
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.
The electrical characterization of these parameters is critical to assess the system performance and provide system level engineers the right data to design their systems and link budgets. However, noise figure measurements at mm-Wave frequencies are not trivial and high uncertainties can be found during the process. This is especially critical in these modules, where every tenth of dB counts and the accuracy of the measurement itself must be minimized.
Any discussion about noise figure measurements includes a wide number of options, instrumentation, and techniques each with their own advantages and limitations. In this tech brief, we focus on non-cryogenic applications, with proven performance, that can be conducted with standard laboratory equipment and easily followed by trained personnel.
