International manufacturer and supplier in the electronics
industry is growing organically and through acquisition and seeking
a 5G Architect. You will be involved in defining technical
requirements and working toward continued architectural and quality
improvement for 5G active antenna products. You will be a member of
the Systems Engineering team where you will utilize your technical
depth to develop detailed integrative designs as well as high-level
conceptual approaches. Relocation will be offered but 100 remote is
not a possibility RESPONSIBILITIES Development of beamforming and
MIMO radio system architectures and antenna array systems for
existing 3G4G wireless standards and developing 5G systems.
Condense high level standards and specifications into detailed
requirements for sub-systems, blocks, and devices. Conduct analysis
and simulation of RF, MIMO, and beamforming behavior from baseband
through the antenna and wireless link using Microwave Office,
Keysight ADS, MatLab, and SimuLink. Conduct chain analysis to
optimize parametric distribution and RF impairment analysis to
ensure system dynamic range and channel fidelity. Perform link
budget analysis to appropriately scale power amplifier and antenna
characteristics. Conduct simulation and analysis of system
throughput for various channel conditions and hardware impairments.
Optimization of functional partitioning between DSP, mixed signal,
and RF blocks. REQUIRED Product development experience in 4G and 5G
Massive MIMO Experience in 5G Massive MIMO Radio Design and Systems
Design Experience on 5G Massive MIMO or Beamforming algorithm
Experience in sub-6 activepassive mMIMO Antenna systems including
calibration algorithms. Experience in active and adaptive
beamforming RF systems. Understanding of receiver and transmitter
functional blocks and capabilities including antennas, power
amplifiers, filters, duplexers, oscillators, frequency converters,
modulators, and demodulators. Wide range of experience in RF system
phased array andor beamforming simulation and analysis using
Microwave Office, Keysight ADS, MatLab, and Simulink. Experience in
link budget analysis, chain analysis, EVM analysis, and throughput
analysis. Experience in analyzing high level system requirements to
extract block level hardware and software level requirements.
Understanding of transmitter and receiver impairments including
sources of thermal noise, phase noise, non-linearities, PIM, group
delay, intermodulation, spurious and simulation of impairment
impact. Understanding of wireless receiver and transmitter
architectures, antennas, and devices. Knowledge of wireless
infrastructure architectures and air interface standards including
LTE and HSPA. Skilled in thorough documentation of requirements and
architectures and presentation of radio architecture concepts.
