This white paper evaluates traditional state of the art platings as well a new proprietary plating, SURO720, developed in partnership by HUBER+SUHNER and Rosenberger.

The family of ZNB vector network analyzers (VNA) from Rohde & Schwarz are the perfect instruments for analyzing RF amplifier small signal linear and non-linear performance. This application note presents information on how to configure and use the R&S^® ZNB vector network analyzer to successfully make accurate and quick measurement of basic RF amplifier parameters.

The low-earth orbit (LEO) satellite realm has spawned an entirely new class of devices requiring innovations in crystal oscillator products to meet performance and price benchmarks. Manufacturers of space-qualified crystal oscillators, like Q-Tech, have developed a range of devices (XO, TCXO, VCXO, and others) to provide optimized price and performance for each orbital application. This paper will delve into the subject with the objective of providing an informed understanding of the elements that go into device selection.

Designing RF systems to operate with wideband modulated signals, like 5G and RADAR, or with a large number of circuits, like active antennas, is challenging. AMCAD Engineering introduces new behavioral models for power amplifiers that include low and high-frequency memory effects allowing robust and accurate DPD algorithm evaluation and validation.

Future technologies and standards will make over-the-air (OTA) testing mandatory. Measurement requirements will change and engineers need a basic understanding of antennas and antenna measurements. But how to get ready for OTA testing? Learn more with our extensive white paper.

5G implementation is accelerating and the promise of higher data rates means more challenges. Demand for more bandwidth increases the probability of interference in mobile devices, driving the need for advanced filtering. Qorvo's BAW filters have evolved to address higher frequencies in shrinking RFFE real estate, while maintaining RF output power.

A Vector Network Analyzer (VNA) natively measures complex S-parameters of a device under test (DUT) in the frequency domain mode by sweeping across various frequency points. While there is an exhaustive list of measurements that can be accomplished in the standard frequency domain mode – using the advanced inverse Chirp z-transformation, the measurements can also be simultaneously analyzed in the time domain mode. This gives the added advantage where the two fundamental modes of analysis can be performed by one single instrument.

On Saturday, May 30th, people across the world watched in awe as SpaceX launched a rocket, designed independently of any government, putting two astronauts into orbit on their way to the International Space Station — the first time in history for any commercial company. Ten years ago, this would have been an unthinkable endeavor for any commercial or private organization.
