International Assignments

  • Visited M/s. COMDEV Wireless Group, U.K, for one year (June 1998 to July 1999) as a Technical Adviser to work on diplexer and multiplexers using dielectric combline resonator at GSM and PCS band. Dual mode and triple mode dielectric resonators filters are first time implemented and demonstrated by me at COMDEV Europe.I was also involved in development of algorithm for generalized filter theory.
  • Visited M/s. Ashvattha Semiconductors, USA from December, 2000 to December, 2001 to conduct research and development on RF IC design for wireless applications. I worked there on design, develop and tested LNA, Mixer and Power Amplifier using SiGe technology for wireless applications. I was also involved in isolation and integration technique for GSM, PCS and GPS band trans/receive circuits in a single chip, which was awarded a US patent for the company.
  • Visited Chung-Ang University, Seoul, Korea as a distinguished visiting Professor from July, 2005 to December, 2005. I was involved in research and teaching on RFIC applied to wireless W-CDMA applications.
