LTE user equipment (UE) receiver performance has significant impact to cellular radio network coverage and capacity. It determines the maximum data throughput across the air interface between the LTE base station (eNB, evolved node B) and the mobile network subscriber UE, thus it determines the total capacity across the air interface. Therefore, it is one of the most important measurements to verify the actual receiver performance of individual devices, and a key metric to compare different devices, in particular.

The Z-Power style resistor gives a better frequency response with similar thermal properties in the same size package. This technology offers designers exciting combinations with ideal thickness, package, aspect ratio and terminal geometry selections. Learn more about the advantages to both RF performance and power handling with Z-Power configured components.

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.

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.
