In-Design Thermal Analysis for MMIC and RF PCB Power Applications

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.

Additive White Gaussian Noise – What Is It & How Can It Integrate into Today’s Advanced Systems?

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.

Key Parameters for Selecting RF Inductors

RF inductor selection involves a number of key parameters including, mounting (surface mount or through-hole), inductance value, current rating, DC resistance (DCR), self-resonant frequency (SRF), Q factor, and temperature rating. While small size is typically desired, the laws of physics limit how small an inductor can be for a given application. Inductance value and current rating are the chief determinants of size. Once they have been calculated, other parameters can be optimized.
