This article details performance measurements vs. predictions of a 16-channel S-band direct sampling receiver design. The design is based on recently released direct sampling analog-to-digital converters (ADCs) clocked at 4 GSPS and sampling in the second Nyquist zone of the converter.

The global transition to 5G is in full swing. Although 5G has primarily been used for smartphones and FWA applications, its potential applications are much broader. 5G will expand in scope to cover many more applications and device types. 5G Redcap will be a key step in this evolution.

Increasing use of small wireless applications, such as Bluetooth, Wifi, Cellular, Positioning, brings challenges to integrate the antennas with maintained performance. There are several techniques for miniaturization of antennas with pros and cons. This paper presents how the PIFA technology can combine small size with good performance and frequency stability.

The aerospace and defense industry relies heavily upon advanced electronic systems for field communications, control, targeting, threat detection, asset tracking, health monitoring, and theater operations. These advanced electronic systems often require multiple, high-fidelity antennas. Those antennas, in turn, require interference free integration for maximum signal strength and reliability. This technical document provides an overview of Altair’s electromagnetics simulation strategies and technologies that support the development of complex electronic systems.

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.

As a result of BTS antennas evolving to integrate 5G technology, antenna measurement techniques and test chamber setups are changing to meet new requirements. This white paper considers the advancing technology and expanding dimensions of 5G BTS and presents a solution in a novel reconfiguration of an anechoic test chamber.

GaN Solid State transistors are utilized in many radar platforms and provide compact and efficient sources of microwave power. CPI has developed a 4 kW X-band SSPA, CPI model VSX3717, for radar applications. This paper will present details of the SSPA amplifier and receiver protector used for airborne radar applications.

The Rohde & Schwarz®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.

Operators are currently undertaking a massive investment in upgrading the infrastructure of both wireline and wireless networks. The need to upgrade and change is fueled by the billions of connected devices belonging to the IoT ecosystem and the new demands they will place on 5G fronthaul networks as operators begin rolling out 5G.

Targeting higher performance and efficiency, the power stages of battery-powered applications must manage high currents while meeting strict power dissipation and size requirements. This white paper illustrates a thermally aware workflow used by STMicroelectronics to optimize an evaluation board deployed in battery-powered electronics that achieved maximum system performance in a short timeframe.
