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.

Mini-Circuits’ BFHK-series of ultra-high stopband rejection LTCC filters accelerates the drive towards RF/microwave circuit miniaturization while completely redefining performance levels achievable by LTCC filters. The BFHK-series of filters now achieves stopband rejections in excess of 90 dB in a surface mount LTCC component consuming just a fraction of the footprint area of even high-k dielectric based planar solutions.

This white paper offers an overview of the fundamentals of THz waves and their properties for various applications with a focus on 6G based communications.

GaN provides higher power density efficiency than traditional silicon in applications requiring high-frequency operation. GaN RF HEMTs are finding applications across all RF market segments rather than just cellular base stations and military radars. In order to maximize these benefits, designers must understand the thermal environment and its limitations.

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.
