Millimeter-wave/RF PA design engineer will have a critical role in developing innovative circuits for Satcom and 5G networks and radar systems, mainly focusing on power amplifiers in silicon technologies. In this highly visible position, the mm-wave/RF PA design engineer will lead the development of the state-of-the-art millimeter-wave transmitter front-ends and work on the circuit topologies for next-generation communication and radar systems. We are looking for highly motivated and talented problem-solvers with strong backgrounds in high-efficiency power amplifier design at microwave/mmwave frequencies as well as solid EM and communication systems background.



Design state-of-the-art power amplifiers at mm-wave frequencies, focusing mainly on silicon technologies.

Develop mm-wave transmitter front-ends and determine the system architecture for the complete signal chain from antenna to bits.

Determine the IC-level implications of system-level requirements of next-generation communication networks.

Design and simulate on-chip EM structures and work on co-optimization of IC/package interfaces.



10+ years of experience in millimeter-wave/RF integrated power amplifier design in SiGe, CMOS, and SOI technologies.

Extensive experience in various high-efficiency power amplifier topologies specifically at high frequency and with fully on-chip integrated implementations.

Strong know-how and hands-on expertise in the analysis and optimization of transmitter front-ends in response to complex modulated waveforms such as 5GNR. This includes practical modeling and circuit simulations of power amplifiers and transmitter chains with time-sampled waveforms.

Solid understanding of RF circuit design fundamentals and RF communication architectures.

Strong fundamentals in electromagnetics theory and communication systems.

Experience in EM simulations both for on-chip and package parts.

Good communication skills and effective teamwork
