      NASDAQ: PWAV Powerwave was a global leader in end-to-end wireless coverage and capacity solutions for commercial and military wireless communications networks. At its peak in 2010, the company had over 2100 employees across 18 locations located in 14 countries with annual revenues approximating $900M. Responsible for the conceptualization, analysis, design, and documentation of a wide range of volume production products including PA modules, feed-forward MCPAs, subracks, cavity filters/duplexers, base station amplifier systems, indoor racks, outdoor enclosures, repeaters, radioheads, antennas, and advanced radio designs between frequencies of 700MHz to 2.6GHz and for protocols including CDMA, GSM, UMTS, W-CDMA, and WiMAX. Select Accomplishments: 12 years of experience in electronics packaging design, thermal and structural analysis, thermal, vibration, and IP testing, and overall product development for the telecom industry. Advanced knowledge of manufacturing methods including punching, stamping, turning, milling, extruding, pultruding, casting, injection molding, and rapid prototyping (SLA, SLS, and 3DP). Extensive knowledge of SolidWorks, Flotherm, and data/process control. Drove mechanical standards to reduce cost, improve time to market, and commonize product development across multiple global design centers. Drove thermal design standards to optimize analysis techniques across multiple global design centers. Developed analytical tools to automate quick first-order thermal analysis of basic and complex thermal systems. Developed an innovative PCBA process to cost-reduce and optimize the design of high power printed circuit cards. This process is now a company-wide standard design technique. Worked on multiple highly successful R&D programs to develop leading edge technologies for the telecom industry. Managed small global teams of junior engineers as a lead and mentor. Show less
