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. Once again, care is taken 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 of expertise and disciplines raging from advanced military AC/DC power management and distribution systems, switching power supplies and inverters to millimeter wave radiometric, spectrum detection, and remote sensing systems. Several members of the CME engineering team have extensive RF design and test experience.
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 Filed Programmable Gate Array (FPGA) and Programmable Logic Device (PLD) experience. This experience covers devices from Actel, Altera, and Xilinx. CME engineers are capable of designing for these devices using schematic capture, very high speed integrated circuit (VHSIC) hardware description language (VHDL), Verilog, or the low-level editing tools provided 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 range to over 11 x 15 inches.
