Job Description

We are looking for a highly motivated RFIC Design Engineer with strong expertise in designing RF integrated circuits, particularly power amplifiers, for wireless communication applications. The ideal candidate will have hands-on experience in the complete RFIC design cycle, from architecture definition and circuit design through layout, tape-out, silicon validation, and characterization. This role requires close collaboration with cross-functional teams to deliver high-performance RF solutions while meeting aggressive performance, quality, and schedule targets.

Responsibilities 

Independently design and develop RFIC power amplifier blocks and other RF components such as drivers, LNAs, VGAs, and bias circuits.
•    Conduct literature reviews and propose innovative architectures to meet stringent design specifications.
•    Optimize designs for maximum performance within technology constraints.
•    Build simulation test benches and perform extensive simulations using Cadence Virtuoso and Keysight ADS.
•    Execute RF layout and EM extraction to accurately capture parasitic effects.
•    Document design procedures and maintain progress reports.
•    Collaborate with and guide other designers, reviewing their work for quality and accuracy.
•    Work with validation engineers to bring up chips in the lab and fine-tune settings to meet specifications.

Requirements

B.Tech. + 5 years or M.Tech. + 3 years of experience in RFIC design.
•    Hands-on experience designing RFIC blocks such as power amplifiers, drivers, LNAs, VGAs, and bias circuits.
•    Proven track record of designing RFIC power amplifiers from scratch.
•    Strong understanding of RF fundamentals, including Gain, NF, IIP3, OP1dB, ACPR, EVM, and PAE.
•    Excellent grasp of DC operating point, frequency response, stability, noise, nonlinearity, efficiency, and load-pull analysis.
•    Proficiency in Keysight ADS and Cadence Virtuoso suite (Schematic, Maestro, ADEXL, Layout XL, Spectre/AMS).
•    Experience in RFIC layout design and EM simulation using tools like ADS Momentum, EMX, HFSS.
•    Successful experience with tape-outs, test bench bring-up, and lab characterization.
•    Strong communication skills and ability to work in a multidisciplinary team.

Preferred Qualifications:
•    Experience in SOI, HBT, or GaAs power amplifier design.
•    Expertise in EM simulations using EMX, Keysight Momentum, and HFSS.
•    Familiarity with SOI, GaAs, and GaN technologies.
•    Knowledge of analog mixed-signal blocks (BGR, op-amps) and Verilog-based RTL.
•    Understanding of post-silicon qualification procedures such as ESD and HTOL.
