Electrical Engineering Capabilities
When not commercially available, Custom Manufacturing &
Engineering™ (CME™) engineers have designed, prototyped, and
demonstrated many of the subsystems required to implement over-all
system architectures. This includes such diverse devices as custom
embedded microprocessor-based controllers, very high frequency(VHF)
data packet radios, power sensing and switching circuitry, inductive
(L), capacitive (C), and Ku band up/down converters. Circuit level
designs are simulated to assure that
they perform as required. A critical objective is to ensure that the subsystems integrate seamlessly
into the overall system.
The Analog/RF group at CME™ is responsible for the design and
development of various commercial and military RF and wireless related
communications product. CME Analog/RF products traverse a wide array
expertise and disciplines ranging from advanced military AC/DC power
management and distribution systems, switching power supplies and
inverters, to millimeter wave radiometric spectrum detection,
remote sensing systems.
Ongoing projects at CME cover a broad portion of the RF spectrum from
about 400 MHz to 55 GHz.
Efforts include the custom design of packet
radio and a passive microwave radiometer.
Several members of the CME engineering team have extensive Field
Programmable Gate Array (FPGA)
and Programmable Logic Device (PLD)
experience. This experience covers devices from Actel, Altera,
Xilinx. CME engineers design for these devices using
schematic capture, very high speed integrated circuit (VHSIC) hardware
description language (VHDL), Verilog, or the low-level editing tools
by each vendor. Current design tools for these devices are
also based on the hardware description language (HDL) protocol.
Prior design experience includes high performance radar pulse
processing algorithms spanning
multiple devices, image processing
algorithms, digital communications, and acoustic signal processing. Input/output (I/O) rates for some of these designs exceeded 200 Mbytes/s,
while others move data
serially at 622 Mbits/s. Some of these FPGA
design efforts have delivered computational performance exceeding five
billion arithmetic operations per second.
CME maintains an in-house board design capability. At present, we use
ORCAD (a printed circuit
board layout and design software package).
CME has designed multi-layer boards that have contained over 1,100
components of about 60 different types on each board, and include both
RF and digital types.
Some boards have been encapsulated into a module
while others are over 11 x 15 inches in size.
