Prior to that he was Principal Engineer RF Systems in Philips Semiconductors Business Line Interconnectivity. At Philips he was responsible for the definition of architecture and IC specifications as well as the development of next generation transceiver chip sets for WLAN and Wireless Interconnectivity applications. He has earlier specified RF IF ASICS for CDMA AMPS TDMA Mobile Phones and has also done extensive Systems simulations for both RF ASICs and CDMA AMPS TDMA base band modems. He has worked on the System design and definition of PWT DECT and Pager transceivers and the associated integrated circuits and has also built various RF transceivers for these applications. His other experience include IEEE 802.4 MAC implementation in software and the design of the digital modem. He completed his Bachelors in Physics Electronics in 1985 and Masters in Electronic Engineering in 1990. In 1988 he was Manager R D with Microtechniques India a company for which he was also a consultant from 1984. Among the many products he developed there a 16-line wireless remote telephone subscriber system had wide spread deployment in India. He joined Philips Semiconductors in 1990 located initially in The Netherlands and currently in Sunnyvale USA. He has been granted 4 patents and applied 15 more . 2 4 17 01 H A basic IS-95 phone design challenge How to reduce phone size and battery drain Smaller Duplexers Lower TX-RX isolation Lower receiver LNA currents Lower IP3 t Transmitter leakage Jammer Cross Modulation noise in Receiver Januning CROSS MOD n leakage NOISE Ạ Cross Modulation Noise EXCEEDS .
