The constantly growing demand for devices with wireless communication ports is pushing devices to operate at increased bandwidths over a wide frequency range. It is becoming increasingly important to ensure every design engineer has an all-purpose radio frequency (RF) amplifier at hand.

This paper provides an introduction to error vector magnitude (EVM), which is the primary metric of modulation accuracy. It discusses the fundamentals of the digital modulation schemes used in modern radio frequency communications systems, in particular, APSK and QAM, the fundamentals of error vector magnitude, and basics of constellation diagrams and how constellation diagrams can often be used to diagnose or troubleshoot the common root causes of EVM.
Multi-tone testing has many benefits. While the multi-tone method was initially implemented to increase the speed of IEC 61000-4-3 radiated immunity testing, it has been found that this method also improves equipment efficiency, offers greater flexibility to truly test the equipment (EUT) under real-world threat conditions, and can be fully compliant to standards.
The prospect of offering large contiguous frequency bands to meet the demand for extremely high data transfer rates in the Tbit/s range is making terahertz (THz) waves a key research area for the next generation of wireless communications (6G). This white paper offers an overview of the fundamentals of THz waves and their properties for various applications with a focus on 6G based communications.
Next-generation electronic systems often demand increased RF power within a smaller footprint to meet demanding performance and size requirements. This paper discusses the impact of operating temperature on RF device performance and presents a thermal analysis solution in which the Cadence Celsius Thermal Solver is integrated with the AWR Design Environment RF/microwave platform.
Full-wave electromagnetic simulation of a Compact Antenna Test Range (CATR) is not trivial given its electrical size. Typically, the reflector geometry is simulated using asymptotic methods using an assumed feed pattern, while RF absorber and its effects are ignored.

Noise is an ever-present factor that affects the performance of wireless systems. In its broadest sense, noise represents undesired electromagnetic (EM) disturbances that can distort information-carrying EM signals. These distortions can originate from internal sources that are generated within electronic systems, as well as natural or man-made external sources, such as atmospheric noise, cosmic noise, and EM interference.
This white paper aims to provide you with a thorough overview of the major aspects of 5G non-terrestrial networks technology and corresponding challenges. We haveincorporated the latest state of the technology involved, representing the current status of the standardization work ongoing in 3GPP.
