RF SystemsEngineer

Location: Austin, TX; Remote

Coherent Logix Incorporated is a world leader of the lowest power, high performance, C-programmable processors for the embedded systems market. Our comprehensive solutions portfolio includes processors, integrated system development tools, optimized libraries, system reference designs, and a customizable system development platform to reduce development complexity and time-to-market. These solutions are designed to support a wide variety of industries, including wireless, wireline, broadcast, computer, automotive, consumer, industrial, medical, military, test and measurement. Further information is available at www.coherentlogix.com.

Description

You will be a member of our dynamic Software Defined Radio (SDR) team; working at fore-front of wireless innovations by leveraging tremendous signal processing power of our SDR platform on RF circuitries. You will be crafting and designing state-of-the-art RF-subsystems for wireless communication system; such as cellular, Wi-Fi, PLC and next generation broadcasting, for emerging applications that requires very high data rate, high efficiency and low latency on our SDR platforms to meet demanding computationally intensive, real-time, high performance, low power and low-cost requirements. The key responsibilities include:
  • Translate system level functional and performance requirements into requirements for the RF sub-system including the breakdown to block level and component level.
  • Analyze the signal chain by means of simulations (e.g., MATLAB, HFSS, ADS) and link budget analysis.
  • Design, simulate, implement and validate RF system subsystem/modules and investigate innovative RF architecture for wireless communication systems and their performance enhancements.
  • Solve complex and interdisciplinary problems that are related to the RF sub-system.
  • Work with vendors, technology suppliers and multi-functional teams to optimize RF system performance.
  • RF sub-system, module, component characterization using RF test & measurement instruments
  • System debugging, analytical and problem-solving.
  • Work with architects, wireless systems engineers, SW engineers, product teams and HW digital designers to define and specify the RF sub-systems / modules.
  • Work with wireless systems engineers and DSP engineers to develop DSP algorithms to correct / improve impairments in RF/analog circuitry, such as calibrations, pre-equalizations, quadrature modulation correction and/or pre-distortion techniques.
  • Provide support for regulatory certifications (FCC/IC/ETSI etc.).
  • Work with chip designers so that our SDR platforms can be improved continuously to support wireless applications.


Qualifications
  • Extensive experience with radio hardware design and/or RF component design, including simulation, schematics capture and PCB layout.
  • Thorough understanding of direct conversion architecture and its impairments correction mechanisms
  • Familiarity with various power amplifier architectures and their associated characteristics; such as power efficiency and linearity
  • Good knowledge of non-linear effects of RF devices and their impacts on wireless system design
  • Working knowledge of OFDM/OFDMA waveforms and MIMO technology; and their impacts on RF
  • Good knowledge of TX and RX performance metrics like ACLR, EVM, spectrum masks, phase noise, receiver sensitivity and RX blocking is a must.
  • Fluent in wireless communications standards, wireless technology and communications market trends
  • Hands on experience with RF circuits and hardware; as well as their characterization and tuning on the lab bench
  • Expert level knowledge in using test instruments; such as Vector Signal Generator (VSA), Vector Signal Analyzer (VSA), RF network analyzer, high speed sampling oscilloscope
  • Experience in analyzing TX / RX chains from RF-baseband interface to antenna and in translating top level requirements into specification items for transceiver building blocks and RF frontend components (e.g., PA, filter, LNA, switches).
  • Experience with DPD and/or envelope tracking is a plus
  • Experience with Python for test setup automation and data analysis is a plus
  • Familiarity with the challenges of development for high-volume manufacturing.
  • Ability to work independently, meet project deadlines and fully documenting work
  • Must have good written and verbal communication skills

Education & Experience
  • MS or Ph.D. in Electrical engineering.
  • 5+ years of relevant experience in the design of RF sub-systems, modules in Wi-Fi and / or cellular architectures.
  • In-depth knowledge of one or more of the following communication standards:
    1. 5G-NR, LTE, WCDMA, GSM
    2. 802.11a/b/g/n/ac/ax, DOCSIS, PLC
    3. Terrestrial Television / Audio Broadcast, such as ATSC3.0, DVB, 5G broadcast
    4. Satellite Communications
