Core Expertise
Analog and Digital Design
The Syndetix Systems Engineering Group is responsible for the design, development and fabrication of analog and digital circuits, components, modules and assemblies for a wide variety of analog, digital and hybrid devices. Among these are embedded controllers, analog and digital modulators, environmental monitors, power distribution, pulse detection and measurement and signal processing.
I/Q Modulator
I/Q Modulator |
Accepts an RF signal from 500 MHz and two differential analog base-band signals to generate wideband I/Q modulated waveforms at RF. On-board X2 multipliers, filters, and amplifiers generate output waveforms from 500 MHz to 4000 MHz at 15dBm.

PLL Multiplier
PLL Multiplier |
Accepts a base-band signal and multiplies it to RF frequencies using PLL techniques. The selections of three individual bands can be accomplished using a simple bit interface that covers the frequency range from 500 MHz to 2000 MHz. To control harmonics and signals, the module includes ceramic low pass filters.

Digital IF Receiver
Digital IF Receiver |
Converts two differential analog IF signals at 170MHz to base-band using sub-sampling, digital down conversion, sampling decimation, and digital filtering. An FPGA computes the two base-band I/Q vectors in a magnitude and angle format using a CORDIC algorithm. The FPGA also computes the phase difference between the two signals, averages the response, and maintains the data in memory mapped registers.

SASSX Mainframe Interface
SASSX Mainframe Interface |
Used as an upgrade to a mature EW suite called SASS that allows the system to use more advanced digitally generated waveforms without modification to the SASS mainframe. Based around an embedded Windows® XP based pentuim-class microprocessor, future module designs are supportable without hardware modification.

Response Timing Module (RTM)
RTM |
This ISA card can be used for two functions depending on the configuration. The Response Timing Module (RTM) generates deep arbitrary pulse group waveforms that can be gated to an external subsystem for the generation of multiple false target techniques. The Real Time Monitor is a pulse detector which accepts a 1PPS and 10 MHz reference from an external GPS receiver and generates time of arrival (TOA) and pulse width (PW) information.
ELINT Preprocessor
ELINT Preprocessor |
Based around a FLEX10K FPGA, the module processes video signals from successive detection log video amplifiers and phase correlators to generate pulse descriptor words that include time of arrival (TOA), pulse width, amplitude, frequency, and angle of arrival (AOA) vectors. The FPGA stores the descriptors in a FIFO bank for real-time retrieval and processing and provides a timing resolution of 10nec. To reduce the number of pulse descriptors, filters are included for minimum and maximum pulse widths.
