Teledyne SP Devices Launches Wideband Digitizer with 6.5 GHz Bandwidth

Configurable digital down-conversion (DDC)
channels with custom digital signal processing (DSP) and continuous
data transfer capabilities.
Teledyne SP Devices, a business unit of Teledyne Technologies
Incorporated (NYSE: TDY), today announced the release of the
ADQ7WB, a dual-channel 12-bit wideband digitizer with 6.5 GHz
analog input bandwidth and 5 giga-sample per second (GSPS) sampling
rate per channel. The wide instantaneous bandwidth and
unprecedented dynamic performance combined with customizable
real-time digital signal processing (DSP) and high data transfer
rates makes it an ideal platform for satellite communication
systems, radar, 5G, and more.
Direct RF Sampling and Multi-Band Support
ADQ7WB allows for direct sampling and transfer of intermediate
frequency (IF) or radio frequency (RF) signals with up to 1 GHz
instantaneous bandwidth within the frequency range 1 MHz to 6.5
GHz. This approach results in improved noise performance and lower
cost as external mixers and local oscillators (LOs) are not needed.
The intuitive digital down-converter firmware option can be
configured to separate up to four individual IF/RF sub-bands and
convert them to baseband for subsequent processing. One example of
use is in Global Navigation Satellite System (GNSS) receivers which
typically use three sub-bands with different center
frequencies.
Optimized for Data Streaming and Computational
Performance
In addition to the real-time onboard signal processing
capabilities, ADQ7WB also supports continuous data streaming to the
host PC or GPU. The GPU peer-to-peer streaming with rates of up to
7 Gbyte/s offers great flexibility to implement real-time signal
processing either in the FPGA, GPU, or both. For spectrum
monitoring applications, functions such as advanced frequency
trigger can be implemented in the FPGA while the GPU is used for
computationally intensive processing such as fast Fourier
transforms (FFTs) with extreme resolution bandwidth. For
applications requiring offline analysis, for example synthetic
aperture radar (SAR) or spectrum recording, ADQ7WB also supports
high-speed streaming to disk storage.
Dynamic Range Advantage
Teledyne SP Devices’ products feature proprietary digital
performance-enhancement technology that provides industry-leading
spurious-free dynamic range (SFDR) performance. The ADX real-time
error-correction IP operates in the background to remove unwanted
performance-degrading artifacts in time-interleaved
analog-to-digital converters (TIADCs). Time-interleaving is
commonly used in many of today’s ADCs and the built-in
error-correction is often insufficient. ADX provides system-level
performance beyond ADC datasheet specifications and therefore
results in competitive advantages for our customers.
