Smartphone manufacturers are introducing full-screen handsets with an 18:9 screen aspect ratio. The form factor hurts antenna performance, resulting in poorer connectivity and lower data rates unless compensated for by the RF front-end. This Qorvo white paper discusses these challenges faced by phone designers and offers solutions.

Techniques for accurate high power RF measurement in excess of 10W. A variety of methods will be considered including RF watt-meters, directional power sensors, directional coupler assemblies and flow calorimeters. The relative uncertainties, advantages and limitations will be considered to match the measurement to the user’s application.

Detailed review of radar waveforms for aerospace and defense, commercial radar systems, including radar sensors used in automotive safety applications. Learn more on continuous waveform trends designed for specific needs, and application differences of continuous wave radar vs. pulse radar systems.

An RF link budget is used to account for all the gains and losses in a telecommunication system — from the transmitter, through the medium (free space, cable, waveguide, fiber, and more), to the receiver. By accounting for the attenuation of the transmitted signal as it propagates through the communication channel, system designers can determine the required signal strength and antenna gain necessary to overcome all feedline and miscellaneous losses in order to ensure an appropriate quality of signal for successful data transmission.

Accelerating 5G standards development is creating pressure for smartphone manufacturers to add 5G new radio (NR) support to handset designs. 5G introduces new challenging requirements and initial mobile deployments will create additional complex RF challenges. Innovative new RF solutions will be required to solve the complex challenges of 5G.

There is a growing requirement for determining the location of emitters in radiomonitoring, security services, military intelligence, etc. Spectral components used in spread-spectrum techniques can only be allocated to a specific emitter if the direction is known. Direction finding is therefore an indispensable first step in radiodetection.
