Overcoming the RF Challenges of Full-Screen Smartphones

Smartphone manufacturers are introducing new full-screen handsets with an 18:9 screen aspect ratio. The form factor impacts antenna performance: reducing antenna space, shorter battery life, connectivity problems and lower data rates. Increased performance is required throughout the RF front-end, compensating for antenna impacts, maintain total radiated power and Rx sensitivity.

System Simulation Primer for RF Link Budget Analysis

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.

Is Your Handset RF Ready for 5G?

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.

Introduction into Theory of Direction Finding

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.

Multi-tone Testing Can Save Both Time and Money

AR RF/Microwave Instrumentation has developed a product which uses a patented test process that adds additional test frequencies, or tones, for each test period, or dwell time.
