Featured White Papers

Bias tees are used extensively to apply DC biasing to RF circuits. This Piconics/Modelithics white paper explains how bias tees can be designed using models that are accurate all the way to mmWave frequencies. Design details and simulated results presented. Measured data is then compared to the simulated performance.

Most ADAS functions rely on radar sensors, and these safety-critical components must function correctly even under the most demanding of RF environments. We have released a white paper describing a test procedure to replicate real life scenarios where the ADAS radar functions are activated during EMS testing and it contains some very interesting results.

In this trend paper, TE Connectivity (TE) will explore the demands and trends in smart surveillance technology within the smart city ecosystem and review what engineers need to consider when designing smart surveillance products and components.

R&S®GSASLP is a satcom analysis and optimization software solution, covering all aspects of modern satellite communications. R&S®GSASLP perfectly supports major parts of the satcom value chain such as satellite system design, transmission planning and transponder usage optimization. R&S®SLP accurately models weather conditions, atmosphere effects and covers all RF transmission impairments of transparent payloads among all satcom bands of interest (C, X, Ku, Ka band etc.).

In broadband bias applications, most inductors do not cover enough impedance bandwidth. Bandwidth can be increased by putting three or four inductors in series, but DC losses and filter complexity increase. Instead, a broadband bias choke provides wide bandwidth in a single inductor package.

Phase noise has been a growing concern for high-performance transceiver designs. This white paper will discuss and analyze the various sources of additive phase noise in RF amplifiers as well as typical application requirements and measurement challenges. Phase noise specifications for a series of MMIC amplifiers are presented.

Automatic Fixture Removal is a simple, accurate way to de-embed measurement fixtures. These are typically used when measuring SMD type components to provide an interface from the VNA test port cables to the DUT. The main challenge when characterizing such components is to completely isolate DUT characteristics from the fixture.

The Rohde & Schwarz®FSWP (FSWP) is a modern, digital signal processing based, phase-noise test set that performs many tasks in parallel in an effort to improve measurements speed. However, several measurement settings drastically affect measurement speed. This paper will discuss these settings and provide suggestions on improving overall measurement speed.
