[Legacy Report] Advances in High Power RF Design
High Power RF design had long been considered "Black Magic" or an art, rather than science. Advances in key technologies have allowed engineers to disprove this myth and establish a new standard of expectations for the industry. It was not uncommon for an RF engineer to spend hours in a lab to tune an amplifier module with his kit of ATC capacitor sticks, foil tape and an x-acto knife. Looking to compensate for parasitic elements and poor device models, trial and error used to be the norm to get a working design and first pass success was only an elusive dream. Hybrid Active Loadpull Systems, 3D - EM simulations and better device models are allowing RF engineers to move into the virtual world, evaluating circuit designs and advanced architectures in simulation before narrowing down on the one design to prototype. This presentation will present an overview of these challenges and the solutions provided by utilizing the advancements in key technologies.
Munawar Kermalli is a BTS Architect at Futurewei Technologies, the American R&D subsidiary of Huawei, where he is responsible for advancing the RF capabilities of Huawei by providing thought leadership and researching novel new architectures. Before joining Huawei, Munawar was with Lucent Technologies in various capacities, including technical manager of an RF design group, lead researcher of a transceiver forward looking research group, RF specification engineer and RF architect of radios and amplifiers in the base station, and lead RF researcher for a novel PA architecture. Prior to Lucent, Munawar was with MPD Technologies, where he started his RF career working on high power amplifier designs, including MPD's first CDMA amplifier and first PCS feedforward amplifier. Munawar holds several patents and has several more that are pending. He was an inducted member of the Alcatel Lucent Technical Academy, recipient of the Huawei Most Valuable Innovation Project, Bell Lab's Silver Award and Team work Award, Wireless Design & Development Award for CDMA BTS Amplifier, and several others. He received his BSEE, summa cum laude from NYU - Polytechnic School of Engineering in 1993 and his MSEE in 1996 and is a member of Eta Kappa Nu and Tau Beta Pi national honor societies.
