This article looks at the semiconductor process and SMT packaging options for the realisation of power amplifier (PA) integrated circuits (ICs) operating at millimeter wave (mmWave) frequencies. It also presents examples of 5G mmWave SMT packaged PA designs.
Much like the 2017 event, this month’s IEEE International Microwave Symposium 2018 (IMS) was abuzz with talk of 5G applications, rollouts, and developments. But nowhere was that focus more singular than Monday’s (June 12) 5G summit, whose speaker lineup looked like a connectivity all-star roster.
The transition from previous 802.11 standards, such as 802.11n and 802.11ac, to 802.11ax adds several new technologies and performance requirements that need to be fully tested. However, there are a number of challenges in designing these test scenarios.
Whether it’s a matter of national security or commercial success, a space plane or a sensor, brilliant people regularly refrain from trumpeting their astounding scientific achievements. It's not always easy or popular, but it's necessary, and I tip my hat top you, secret-keepers.
NR is billed as a more capable air interface, and will need to operate in both the frequencies below 6 GHz and above 24 GHz (mmWave) with a frame structure supporting both TDD and FDD, as well as operate in both licensed and unlicensed spectrum.

ALPHA – Route des Lasers & des Hyperfréquences, a technology cluster specializing in photonics, microwave and digital technologies, recently announces it will bring six cluster members to the International Microwave Symposium (IMS) 2018, taking place on June 10 – 15, in Philadelphia (PA).
Next-generation 4G/5G telecommunication systems require power amplifiers (PAs) to operate with high efficiency over a wide frequency range to provide multiband and multi-standard concurrent operation. This application note describes the design of an innovative Doherty amplifier architecture using 200-W high-efficiency broadband 1.8-2.7 GHz GaN high-electron mobility transistor (HEMT) technology, which achieved average efficiencies of 50-60 percent for output powers up to 100 W and significantly reduced the cost, size, and power consumption of the transmitters. The designers used the NI AWR Design Environment platform, specifically Microwave Office circuit design software.
Every time a new cellular phone standard comes out, we see new claims about the “end of Wi-Fi.” When 3G was announced, the promise was that it would make Wi‑Fi (802.11b) redundant, which clearly turned out to be incorrect. With 4G (LTE), this story repeated itself and claimed it would put Wi‑Fi (802.11ac) in the shredder. And now the 5G message is that it will cover both the inside and outside of homes and buildings. It’s almost as though Wi‑Fi will soon no longer be needed. This begs the question: What will be the impact of the next generation of Wi‑Fi, Wi-Fi 6 (802.11ax)? Do we even need it in the 5G/wireless landscape? This article discusses the answers.
Corry Micronics offers an array of components for 5G network filtering applications.
New technologies being deployed will need to rely on the performance of both high-power amplifiers on the transmit side, and low noise amplifiers on the receive side. Quantifying critical specifications like noise figure and noise power ratio can give radio and receiver designers a deep understanding of how the overall system will perform. Noisecom noises sources generate the broadband noise required to do this type of benchmarking and quantify component and system performance across the microwave and millimeter bands.
Compiled by The Next Generation Mobile Networks (NGMN) Alliance’s 5G Extreme Requirements task force – which includes contributors such as Jaya Rao, Huawei; Joachim Sachs, Ericsson; Alan Stidwell, David Lister, Vodafone; and Javan Erfanian, Bell Canada -- this white paper aims to highlight what implications and trade-offs related to the delivery of new 5G services are relevant for mobile network operators.
5G technologies promise to deliver higher data throughput, extremely low latency, and speeds up to 100 times faster than 4G. This paper explores the practical first steps of a roll out and focuses on the spectrum below 6 GHz as standards for millimeter-wave applications have yet to be determined.
