Line manager
responsible for supervising four design engineers. Conducted biannual
performance reviews. ·
Lead
design/project engineer for a SiGe BiCMOS direct conversion dual band transmitter RFIC for
AMPS, CDMA, PCS, and WCDMA applications.
The design includes direct conversion upconverter,
RF VGA, CELL and PCS band driver amplifiers, TX PLL, TX VCO, and RX PLL. Developed and evaluated direct
conversion transmitter architecture in three different silicon technologies. Oversaw a team of five design
engineers. Designed and modeled
integrated copper spiral inductors.
