This white paper offers an overview of the advantages of gallium nitride (GaN) for high and moderate power levels in Ka-band satellite communications applications. The paper includes a discussion of the RF power amplification challenges presented by Ka-band data transmission, including the need for high power transmission, wide bandwidth and high linearity. Altum RF’s family of GaN amplifiers is presented, with illustrations of how these components suit specific scenarios within Ka-band satcom applications. The paper concludes with a demonstration of the importance of accurate modelling of electrical and thermal effects for these applications, given the high power levels and high frequencies required.

CMT VNAs are USB-based and do not have built-in computers. There are benefits to having the VNA measurement module separate from the processing module. The USB VNAs must run with an external PC and the VNA to work. You can consider the VNA software as the driver for VNAs.

Embedded systems, used in applications ranging from toys to advanced aircraft, use microcontrollers to execute specialized operations within a more complex system. Most microcontrollers are mixed signal devices using a combination of analog and digital signals.

Innovation in next-generation mobile devices creates significant challenges for antenna implementation. 5G handsets have more than twice as many RF paths, and new industrial designs and button replacement add space constraints. Qorvo Antenna Solutions Reimagined (QASR) helps navigate space, design and performance challenges to harness the true power of antennas.

5G deployments have only recently started, and releases beyond R15 will continue to tap into the tremendous potential of 5G. However, as a new generation of cellular technology typically appears every 8-10 years, 6G can be expected around 2030. Download this white paper to explore the evolution from 5G to 6G from a service, air interface and network perspective.

3D-ICs integrate many dies that are densely packed, which leads to heat generation that causes performance issues. This white paper helps designers understand the cross-fabric thermal challenges introduced by 3D-ICs and explains how the Cadence® Celsius™ Thermal Solver helps designers analyze and develop strategies to mitigate this impact.

The spectral environment is quickly changing today. It’s becoming more crowded, which is resulting in an increase in spectral noise. This is presenting a variety of new challenges for RF designers, both in terms of the architecture and power needed to transmit and receive signals and the types of jobs filters need to perform in receivers (Rx) and transmitters (Tx).
