Integrated Doherty PAs for Cellular and mmWave Applications

Jangheon Kim and Abdulrhman M. S. Ahmed
Sunday, January 10 | Time: TBD

In this workshop, we will discuss cellular infrastructure trends, 5G spectrum, and mMIMO power amplifier requirements. We will present the advantages and disadvantages of the discrete transistor versus the integrated mMIMO power amplifier approach. Details will also be provided about GaN Doherty power amplifier design topologies. Furthermore, Wolfspeed 5G mMIMO GaN on SiC integrated power amplifier examples are shown.

Digital Predistortion for 5G MIMO Wireless Transmitters

John Wood
Tuesday, January 12 | Time: TBD

In this workshop, we will discuss wireless infrastructure; where we are now and where we’re heading. We will detail some challenges with DPD linearization that 5G will bring; bandwidth, mMIMO, and TDD operation. Also, how the industry needs some DPD development to meet the linearity (and other performance) specifications as well as partnerships between industry sectors to make 5G a success.

How to Enable a Successful RF Broadband Design for a 500 – 3000 MHz Amplifier

Live January 14th at 12:00 EST | Today’s modern communications systems require amplifiers that meet a high level of performance over much broader frequency spectrums. This presentation will describe how thermal considerations can set performance thresholds for amplifiers, why broadband designs are difficult, and a methodical design flow to achieve a balanced performance across the target band.

Thermal Considerations for High-Power GaN RF Amplifiers

Many RF applications require very long lifetimes with typical military and telecom use cases demanding more than 10 years of operation. Junction temperature Tj, or the temperature of the base semiconductor in the device, plays an important role in device reliability as does the substrate material in keeping the base semiconductor cool.

Primer on BLOS Troposcatter Communications

The latest troposcatter communication system requirements place substantial challenges on RF designers and suppliers, with simultaneous requisites for low weight, ruggedness, reliability, compact size, high bandwidth, excellent electrical performance, and efficiency. Fortunately, Wolfspeed has an innovative line of gallium nitride (GaN) high-electron-mobility transistor (HEMT) power amplifier (PA) solutions.

Why Wolfspeed?

GaN Expertise

We created the industry’s first GaN HEMT on Silicon Carbide and for the last 20 years have focused on investing in tomorrow’s innovative RF solutions by partnering with the world’s designers to improve system size, weight, and power.

Assortment

As a pioneer in gallium nitride semiconductors, we now field a broad portfolio of the most capable next-generation, GaN on SiC based HEMTs (as packaged & bare die), MMIC power amplifiers, as well as LDMOS devices for all your RF system design needs.

Capacity

We are the only vertically-integrated semiconductor manufacturer and control 100% of our GaN and SiC material supply. We doubled our production capacity in 2018, are on track to double capacity again by the end of 2020, and will continue to expand our capacity to meet the expected market growth by 2024.
