Jonathan Shilling Email and Phone Number

• Working as senior development engineer on HyperLynx SI/PI & Advanced Solvers simulation software for pre- and post-layout verification using full-wave & hybrid electromagnetic field solvers.• Responsible for test-driven development and creating test plans to exercise and detect defects in new product functionality via functional, performance, and automated regression testing.• Verify compliance with JEDEC & IEEE specifications and methodology accuracy in COM, eye diagram, jitter, and timing analysis in designs featuring IBIS-AMI, HSPICE, ELDO, VHDL, & VERILOG modeling.

• Hardware design engineer responsible for design & development through all life cycle stages (concept, design, & production release) of RF broadband amplifiers, nodes, and 75Ω CATV products employed in Hybrid Fiber Coax (HFC), RF over Glass (RFoG), and Fiber Deep (FD) networks.• Genesys/ADS Simulation and design of higher-order filters, equalization circuits, impedance matching networks, and both differential and single-ended amplification stages.• EM modeling of PCB layouts and connectors using CST’s PCB & Microwave studio.• Testing and device characterization including frequency response, return loss, noise figure, non-linear distortion, signal to noise ratio, QAM modulation error ratio, and thermal response.• Developed a Fiber and Cable Evaluator C# based program to interface with network analyzer's to control settings, capture data, and normalize various cable and linear tilt profiles from DUT's response characteristics.

• Responsible for concept-to-production development of OCXO-305, an ultra-low phase noise oven controlled crystal oscillator. • Design and development of supporting circuitry including B mode traps, BJT amplifiers, resonant circuits, and phase-shift networks.• PCB layout & schematic capture in DxDesigner.• Extensive testing including phase noise and allen deviation characterization.• Familiarity with I2C, SPI, RS-232, and RS-485 interfaces.

• Test engineer working on InfiniBand high-speed active optical cables that completed extensive jitter and BER testing to characterize transceiver performance and optimize equalization settings.
