Low Loss, High Isolation mmWave Switch MMICs

by Graham Pearson and Liam Devlin, Plextek RFI Many emerging applications at Ka-band and above, such as 5G and broadband satellite communications, are adopting architectures that require low-loss, high-linearity switches. FET-based switches on both GaAs and SOI (Silicon on Insulator) are used to realize high performance, low-loss switches at RF frequencies. They have been used […]

A First Look at Modern Macrocell PAs and Their Practical Implementation Considerations

by Pasternack The onslaught of 5G-related technologies has led to a plethora of material covering small form factor transceivers for user equirement and mobile devices. While many of these design constraints do not necessarily apply to macro BSs, some do. This article aims to provide some more details around the design considerations for PAs for […]

Defeating Interference in a Connected World

by Fairview Microwave The wireless industry may be short of available spectrum below 6 GHz, but it has interference in abundance, and there’s even more coming in the future. It’s not just from 5G, the most likely culprit, but also from the enormous number of wireless-enabled devices employed by IoT networks, connected vehicles, and expansion […]

Filtering out Common Mode Noise in Congested Environments with Monolithic EMI Filters

by Johanson Dielectrics A multitude of factors are conspiring to increase the amount of “noise” interference that can disturb the functionality and even damage electronic devices, starting with the sheer number used in our vicinity at any given time.   Today’s automobiles provide a prime example.  In a single vehicle you can find Wi-Fi, Bluetooth®, […]

The Reality of Millimeter Wavelength for 5G

by Pasternack  Amid the attention to the coming fifth generation of “cellular” technology, the use of spectrum at 28 GHz and higher is generating some of the attention. Most media coverage recites the well-known challenges associated operating at millimeter wavelengths and how it will require a huge number of small-cell case stations, massive MIMO, phased-array […]

Applications of Microwave Radiation in the Diagnosis and Treatment of Cancer: A Brief Review

by Dr. Huma Rasheed, Fawad Maqbool and Mick Syed, AmpliTech Inc. Radio Frequency Microwaves (RFM) exert various effects on the biological system and possess a great impact in medical applications, for instance by heating, altering chemical reactions, or inducing electrical current in tissues and cells. The knowledge of temperature-dependent electrical properties of biological tissues is […]
