Chris Shepherd - Systems Engineer

Work Record


RF Micro Devices (2006-present)

After two years at Jennic Chris became an Applications Engineer at RF Micro Devices where he works on their Slice frequency converter and modulator products.

Jennic (2004-2006)

Following the discontinuation of cellular chip developments at Zarlink Chris spent some time as a systems design contractor working for Jennic in Sheffield (now part of NXP) working on the design of their second generation ZigBee chips and modules.

Zarlink Semiconductor (1998-2004)

In February 1998 GEC Plessey Semiconductors was taken over by Mitel Semiconductor (Kanata, Canada), subsequently renamed Zarlink Semiconductor. Chris joined the Systems Group at Swindon and moved there in May 1999. He was subsequently incorporated into the Systems Group within the User Access Division where he lead systems design activities on all types of cellular systems (AMPS, TDMA, WCDMA, CDMA2000). In his time with Zarlink he travelled extensively in the US and Far East in customer liaison roles. Chris worked on low cost transceiver chips for the American TDMA/GAIT markets and 3G systems for Europe and the Far East. Zarlink stopped their design of cellular chips in 2003.

GEC/Plessey Semiconductor (1995-1998)

In January 1995 Chris moved into the Wireless LAN department under Terry Aliwell at Lincoln. He worked on designing WLAN's, factory support for WLAN's, support for Car Alarm production, systems support for Pagers and design support for Code Division Multiple Access systems and Bluetooth Wireless Local Area Networks.

GEC/Plessey Telecommunications (1990-1995)

In 1990 Chris moved from research into the world of industry, and joined GEC Plessey Telecommunications (GPT) in Beeston, just outside Nottingham, to work on cordless telecommunications systems. Chris worked on the standards setting body for the Physical Layer of the Digital European Cordless Telecommunications (DECT) system and the testing specifications for the European second generation cordless telephone (CT2) standard. He was also part of the design team that developed the CT2 phone used in the Rabbit Telepoint network and cordless office telephones. In 1993 part of the CT2 development team moved to Coventry. At this time Chris was working on the use of CT2 technology in the emerging Wireless in the Local Loop (WLL) market and travelled to America and China in a technical support role. He helped develop the low cost CT2 base stations for this application as well as the subscriber terminal - learning a lot about how telephone networks work in the process. Chris did courses on telephone networks, ISDN and digital networks whilst there. During his time at GPT Chris obtained a Diploma in "Manufacturing: Management and Technology" with the Open University.

Roke Manor Research (1983-1990)

After leaving university Chris went to work for Plessey Research at Roke Manor near Romsey in Hampshire. Chris worked on a wide variety of projects including wideband optical instrumentation receivers and radio communications ranging from HF communications system design through to propagation measurements at 60GHz. He was (co-)author of a number of papers on this subject in the mid-eighties. It was during his time at Roke Manor Chris became a Chartered Member of the Institution of Electronics and Radio Engineers (IERE), now the Institution of Electrical Engineers (IEE).
