Sirific Wireless CTO Tajinder Manku to Present at 2006 RFIC Symposium

Richardson, Texas – May 31, 2006 – Sirific Wireless Limited chief technology officer (CTO) and founder Tajinder Manku will present at the tenth-annual Radio Frequency Integrated Circuit (RFIC) Symposium in San Francisco on June 11-13, held in conjunction with the IEEE Microwave Theory and Techniques Society (MTT-S) International Microwave Symposium.

Dr. Manku will present "3G/HSDPA Radio Transceiver Chipset: Design Issues and Challenges" on Sunday, June 11. The discussion, one of five selected for this session on system architectures and design guidelines, will identify design and performance problems associated with the integration of single-chip 3.5G HEDGE (HSDPA/WCDMA/EDGE) transceivers. "The opportunity for advancing next-generation cellular transceivers to improve overall system performance lies in the ability to implement innovations in receive and transmit architectures in a CMOS process," said Dr. Manku. "I am pleased to be speaking at this event and look forward sharing Sirific’s expertise with the industry."

Sirific has applied this expertise in 130-nm CMOS RFIC design to its Nexus™ III family of single-chip 3.5G HEDGE transceivers that support transmit and receive operations, including receive diversity, in seven WCDMA bands (I - VI and VIII), as well as all four GSM / EDGE bands. All Nexus III transceivers incorporate a proven linear direct up-conversion architecture that enables a low-noise, power-efficient multi-band transmitter design that interfaces directly to standard linear power amplifiers. Another common feature of Nexus™ III transceivers is a multi-band direct down-conversion receiver architecture that supports DigRF 2.5G and compressed mode operation for smooth handoff between 3.5G and 2.5G networks.

Dr. Manku has more than 15 years of experience with RFIC design, development and assessment, and has consulted for a number of companies including Lucent, Motorola, Nortel, PMC-Sierra, TSMC and Mitel. While leading the RF Technology Group at the University of Waterloo (UW), Dr. Manku was awarded more than 30 patents at different stages and published more than 80 papers. His technical background includes solid state devices, IC design and wireless system design. He earned a Bachelor of Science in solid state physics and a Ph.D. from UW.
