Optimizing Beamforming Through Intelligent Integration
In emerging communications standards, integration and faster array reconfiguration bring tangible benefits to beamforming systems employing simultaneous multi-user techniques and multi-element antenna arrays. These benefits include faster tracking of users, higher data rates and lower power consumption through improved signal strength. The key to achieving this performance will be more intelligent arrays where more of the array configuration is delegated to the gain and phase shifter elements, and increasing the accuracy of these elements. This session will explore how Peregrine Semiconductor’s UltraCMOS® technology and intelligent integration allow increased resolution and memory elements to be added to traditional core chips. These integrated core chips allow preloading of configurations that can be automatically cycled at high speeds, resulting in more accurate beam formation.
Optimizing Doherty Amplifier Yield & Performance Through Integrated Phase & Amplitude Control
Any engineer who’s been tasked with implementing a Doherty power amplifier for a wireless base-station transmitter can attest to the difficulties associated with Doherty amplifier optimization. Any mismatch or misalignment in phase and amplitude between the Doherty architecture’s carrier and peaking paths can quickly contribute to higher manufacturing costs and degradation of the overall performance. This session will explain how to optimize Doherty amplifier yield and performance through a monolithic solution that offers integrated phase and amplitude control. By using a monolithic controller, wireless-infrastructure vendors can increase system performance, reduce bill of materials (BOM) costs, improve system reliability and maximize tuning flexibility.
Why High Frequency RF Applications Need CMOS Technology
CMOS is now extending its reach to the microwave and millimeter frequency ranges and displacing gallium arsenide (GaAs) and other compound solutions that have historically serviced these high frequency markets. From 5G and wireless backhaul to automotive radar, high frequency applications are on the rise. CMOS offers many performance advantages over traditional III-V MMIC technology offerings, and this session will explore the benefits of CMOS technology in the microwave and millimeter product space. This workshop will also discuss the technology, device and design factors affecting high frequency IC performance.
