OBJECTIVE:

Motivated and versatile Electronics Engineer specializing in analog design and Visual Basic.

PROFESSIONAL EXPERIENCE :

Xena Electronics, Woodland, CA
1998-2001
STRATEGIC MARKETING ENGINEER
DESIGN AND DEVELOPMENT ENGINEER

Xena Electronics developed cellular products such as hands-free kits for cellular phones and Wireless Local Loop WLL .

Designed an Automatic Test Equipment ATE stand that tested a number of ORA s products such as hands-free kits and WLL. The stand consisted of a 11X17 two layer board stuffed with numerous analog and digital circuits including a power supply and 8051 processor. The board interfaced to an I/O board inside the PC.
Wrote and designed a self test and calibration program for the ATE, including a routine to output the same amplitude sine wave regardless of which ATE board or PC was used.
Wrote numerous Visual Basic programs to make the ATE versatile enough to 100 test a number of products and simple enough to use that anyone could run the test stand with minimal training. The data was automatically logged into Excel for statistical analysis. Added menu driven trouble-shooting capabilities to the ATE program so that a technician with minimal training and with no schematic could repair the Unit Under Test UUT . Used ATE to down load an assembly routine into 8051 of the UUT for self-testing.
As a Marketing Engineer, I brought a wireless headset into Ora based on magnetic induction. I read about the chip set in EDN magazine, in which ORA then purchased 100 sample units for resale, while I worked on developing the next generation design.
In charge of MIS; setting up PCs, email accounts, and application software.
Provided extensive technical support to sales department for RF based cellular boosters.
Project Engineer for the Fujitsu project that consisted of an Interface Bus circuit based on the 8051 , for communication between various phones such as the Nokia 6190 and the car voice activated Fujitsu stereo units. Rewrote the code C and assembly and redesigned the Interface Bus per customer requests.
Took over the Synacom project after the customer had given ORA a drop dead date. As an engineer, redesigned the hardware and rewrote the embedded C code. As a product manager, kept track of schedule to make sure all 300 components and materials would be in on time for board stuffing and unit assembly. As a project engineer, trained and supervised over 20 people to assemble and test the units. As the 500 units were being tested, I personally trouble shot and then directed the repair of 200 units. The result was that ORA was able to deliver all 500 units to the customer with 100 quality within the abbreviated time frame.

Variations on the output current of current reference block due to power supply, temperature and process were very small. DAC is voltage to current converter and the output current has binary weight according to input bit. All the blocks were simulated in both SSIM and BSIM models. To know the dynamic behavior of PLL digital and analog blocks are simulated in mixed signal environment Verimix . My responsibility was to setup for interface between digital and analog blocks. Digital simulations were performed using Verilog-XL and the analog simulations were done in SPICE.

Principal RF Engineer

Involved with "skunkworks" GSM Smart Antenna system effort. Project included travel to the U.K. for training/consulting time with a GSM organization called MAC Multiple Access Communications . Responsible for system RX and TX RF Hardware development including the following:

RX side RF switch matrix four RF inputs and 12 RF outputs with drop-in, all surface-mount RF components M/A Com LNA s, Alpha splitters/digital attenuators/GaAs switches for operation in either the EGSM, DCS-1800, or PCS-1900 frequency bands. Design included the following: an Altera EPF10K20 programmable logic device for control of all switching functions in accordance with the GSM TDMA format, a pilot tone and RF detector circuitry for path integrity checks, digital attenuators on all RF paths for path gain balance to within 0.5 dB. The entire receive side noise figure, gain, and intercept point were set by this design. 12 layer FR-4 PCB.
"uplink" scan receiver essentially a "narrowband, IF-digitized" digital receiver with drop-in RF components for all three frequency bands mentioned above. The receiver chain consists of a single down-convert to a 200 kHz BW SAW filter center frequency of 199 MHz and then into a high speed A-to-D converter Analog Devices AD6600, encode rate = 13MHz . After the AD6600 was an Analog Devices "decimating receiver" AD6620 . The AD6620 contains a numerically controlled oscillator, which performs a second down-conversion, and then three stages of digital filtering at base-band for extreme rejection of GSM "blocker" signals. The design also included PLL design centered around the National Semiconductor LMX2320 synthesizer chip and a M/A Com VCO for good phase noise performance. 8 layer FR-4 construction. ETSI GSM 5.05 specification guiding design.
"downlink" scan receiver design for monitoring communications from the TX ports of the GSM base station transceivers. Essentially the design mimics a mobile phone by utilizing half of the Analog Devices GSM chip set ADmsp415 chip set . Design included the National Semiconductor LMX2331A dual synthesizer chip, Analog Devices AD6459 IF subsystem chip mixer, amplifier, I and Q demodulators, etc. , and an Analog Devices AD6421 chip half of the ADmsp415 chip set . This design provided GSM timing and control channel information to the "downlink processor board" of our system.
TX combiner board. This board s function is to combine four 40 watt RF signals 925-960 MHz from GSM base station TX ports. Very simple from a schematic standpoint but more difficult from a heat dissipation and mechanical standpoint. The board utilized Anaren 3 dB Xingers and 6 dB couplers, RF Power Components, Inc. 100 watt and 150 watt "waste" loads, Rogers 4350 low loss dielectric substrate, AMP 2mm Hard Metric style backplane connectors and a massive heat sink approximately 10" by 16" for heat dissipation from the "waste" loads. Single layer microstrip construction. Worked with Mechanical Engineers to define heatsink.
TX side switch matrix and high power attenuator project 925 to 960 MHz . This design built upon previously developed prototypes and utilized two versions of M/A Com high power PIN diodes for transmission/attenuation of up to 40 watt RF signals. The design consisted of two SP5T single pole five throw switches and two high power attenuators DAC voltage control , controlled by an Altera EPM7256A programmable logic device. The SP5T s were very frequency sensitive, requiring l/2 and l/4 sections and judiciously placed tuning stubs for tuning out diode and other surface mount component parasitics. Design also required a switching power supply, centered around Linear Technologies "ultra-quiet" LT1533 chip, to go from +24 VDC to -75 VDC for high reverse bias of PIN diodes. Measurements were made on a prototype, RF modelling was performed using Ansoft Serenade software and schematic entry was completed. Layout for this design was to begin in April.

DSP Controlled Soft-switching Inverters for Motor Drive Variable Frequency and UPS

Soft switching topologies for inverters are being studied, compared and simulated by Pspice, and prototypes built.
A three-phase Auxiliary Resonant Commutated Pole ARCP inverter variable speed motor drive, a single phase Resonant Snubber Inverter for UPS and a coupled inductor zero-voltage switching three-phase inverter were built.
This control scenario detects the load current direction at the output of the inverter to define the state of the inverter and control the auxiliary switches accordingly.
These inverters are controlled by Analog Device !/ s ADMC401 motor control DSP, which generates space vector PWM signal at 20 KHz.
With soft-switching technique, these inverters have the advantage of smooth commutation, reduced stress on the switches and EMI and enhanced efficiency.
The soft switching technique, featuring independent control of each phase of inverter, can be used in field orientation control motor drive as well.

Series Resonant Inverter for Ceramic Ballasted CO2 Laser

A prototype full-bridge Series-Resonant Converter of 3KW to7KW was built for a high frequency discharge CO2 laser.
The electrodes of the laser was covered by a layer of ceramic, thus formed a capacitor with the gaseous load flowing through.
This capacitive load formed the main part of the resonance tank, which could be approximated as capacitors and resistor at the secondary side of the transformer.
The converter operates at the resonant frequency with zero current switching.
