RF/Analog Design Engineer

Ethertronics is seeking an RFIC/Analog Design Engineer. This Design engineer will be responsible for the development of RF LNAs and analog circuits in SOI or CMOS technology for front-end modules applications. Candidate will work in a team environment and will provide technical leadership in all phases of product development, including product definition, architecture, system, transistor-level circuit design, layout and/or layout supervision, lab debug and production support. Knowledge of switch design, filter, analog blocks and module design wireless systems is a plus. Familiarity with WIFI standards will be useful. The candidate must be able to work well with other design engineers, system engineers and layout designers. The candidate will face challenging tasks to meet critical performance parameters in the design state-of-the-art LNAs and Switches. Very good understanding of semiconductor physics and strong circuit simulation skills utilizing the Cadence environment are necessary.



This RF design engineer position will focus on development of front-end receiver circuitry including Low Noise Amplifiers, RF switches, Peak detectors, RF filters, BGAP, LDOs and etc.
