I am technically astute and aggressive especially in the areas of transceiver, oscillator, and synthesizer design and development. I thrive on creative challenges, am self-motivated am a team player with the desire to make substantial contributions to my employer.

Software Simulation Tools: Experienced with ADS and Eagleware, Microwave Office, and HFSS for EM simulation, schematic capture, and PCB layout of microwave components and network systems analysis. Also familiar with Matlab and Math CAD.

Patents: Currently awarded 8 patents and 16 others are pending.
Experience: 6/02/08 to Present: EMS Technologies, Defense and Space Systems
Position: Staff RF and Microwave Design Engineer.

Projects: Geodesic Cone Slot Antenna Array with a polarizer and T/R module. Designed the T/R switch Module. The operating frequency is around Ku band. Single Channel Monopulse Beamformer that takes 4 channels with random phases and amplitudes, trim the phases and amplitudes and combine and amplify the resultant signal. Designed the Beamformer and laid out the prototype PCB.

Transceiver for the Iridium Cross Link Satellites at K band half duplex (transmit and receive use the same frequency with 50% duty cycle). The Feeder Link operates at Ku band transmit, and Ka band receive full duplex operation. Designed the synthesizers, transmit and the receive chains for the T/R switch module.

Tested and located the X-Band Satellite System and tracked the beacon. Measured the received signal strength of the beacon, using slot array antenna equipped with a polarizer and T/R switch module.

Position: Senior Technical Staff Member
Project: Wireless Fidelity (Wi-Fi)/Broadband Power Line (BPL) communication systems, and Worldwide Interoperability for Microwave Access (Wi-Max) OFDM radio Communication Systems:
I was involved in the Wi-Fi and Wi-Max broadband orthogonal frequency division multiplex (OFDM) radio system development and testing covering the 802.11a/b/g in the unlicensed band, 2.4 GHz and 5 GHz. I also designed the antennas operating in these bands. I was involved in the Broadband Power line (BPL) Communication system development and testing using the HF frequency (2-30 MHz).I personally characterized the effects of various sources of interference for integrated Wi-Fi/BPL communication systems.

Project: Point-to-Point (PTP), Point-to-Multipoint (PTM) Radios, and Free Space Optical Communication Systems:
I worked on the Point-to-Point, Point-to-Multipoint radio system development and test, and Free Space Optical communication system testing and certification. I worked on and evaluated the 38 GHz OC-3 point-to-point radio systems, 38 GHz OC-3 radio SONET ring, 38 GHz point-to-multipoint radio systems, and the free space optical communication system at 1400 - 1600 nm for voice, data and video. I developed the acceptance test procedures and testbeds for the different radios and optical communication systems. I took the lead in their testing and characterization.

Project: Cable Modem and HITS Satellites Receiver System:
I was involved in the installation of HITS Satellite parabolic antenna and LNB for HITS Satellite signal reception and integration to the cable modem/TV system for signal and image analysis. I completed General Instrument's course on Broadband communication systems. The following topics were covered: unity gain amplifier design, strand mapping, node spotting, network design, powering the system, different types of coaxial cables and their impedances, and all the component symbols. I was involved in R&D to redesign AT&T's Cable Headend for bidirectional voice and data, and video communication.
