From The Editor
The Week in 5G: 8/27/2019 — South Korea’s KT Addresses 5G Device Battery Drain, Huawei Launches AI Processor and Computing Framework, Verizon Makes Deal To Bolster Its Indoor 5G
 
By Ed Biller

Plus, Switzerland moves to the forefront of 5G rollout, Duubee launches its first 5G commercial terminal, Finland's HMD Global looks to slash 5G handset prices, and more, all in this edition of The Week in 5G.  

Spotlight On GaN Technology
Highs And Lows Of Electronic Warfare
Article | By Mike Lee, dB Control

The next chapter of electronic warfare is all about precision and low visibility. Col. Mark Dotson said the Army’s new EW strategy is centered on, “using low power to affect the signal and to affect it in such a way that it may not even be detectable that you’re interfering with what they’re doing.”

Using Broadband Bypass Capacitors For High-Speed Optical And Millimeter-Wave
Article | Knowles Precision Devices DLI

This article examines the use of broadband bypass capacitors for use in microwave and millimeter-wave frequencies, especially those used in RF applications and optical communications.

Doherty, Balanced, Push-Pull, And Spatial Amplifier Performance Enhancement
Application Note | Rohde & Schwarz GmbH & Co. KG

This application note presents a hybrid simulation-/measurement-based development methodology used to achieve enhanced amplifier performance with linear form of predistortion. The approach shown may be combined with DPD to achieve an even better result. It may also be used to lower DPD requirements.

Automatic And Fail-Safe Biasing Of GaN Transistors
Application Note | Integra Technologies, Inc.

Since GaN HEMT transistors are depletion mode devices, it is critical to supply a negative voltage to the gate before any positive voltage is applied to the drain, otherwise the transistor will draw its maximum possible drain current from the supply.

Using An Application Fixture (CGHV27060MP-AMP3) For Tactical Communication Radios
Application Note | Wolfspeed, A Cree Company

Wolfspeed, a Cree Company, has developed an application circuit that demonstrates the ability for the CGHV27060MP to operate between 800 MHz to 2700 MHz for tactical communication power amplifier applications.
