Multi-Antenna Systems

D-TA’s 10 Gigabit Sensor Processing technology has revolutionized sensor system

development. It has created future-proof system architectures that scale linearly as bandwidth

and channel-count increase. This is particularly true for multi-antenna systems. Virtually any

multi-antenna system can be readily configured using solutions from D-TA. D-TA products

offer:

• Both Receive & Transmit Functions;

• Wide Frequency Tuning Range (For COMINT & ELINT Signal Processing);

• Independent or Phase-Coherent Tuning;

• Wideband & Ultra-Wideband (40MHz, 80 MHz, 500 MHz & Beyond) Solutions;

• Built-In Programmable Digital Down Conversion (for BW selection);

• Real-Time Recording & Playback of Baseband (I &Q) Data;

• Built-In Digital Up Conversion (for analog playback);

• Replicated 10 GbE Links for Processing While Recording;

• Fully Integrated & Tested Configurations;

• No User Development Required for Recording, Playback and Post-processing.

For real-time user application development in a multi-core environment D-TA supplies

Software Development Kit (SDK), example cores and also hands-on training (if required). The

following slides demonstrate multi-antenna system configurations for Signal Intercept,

Beamforming, DF & Other Processing.

Portable RFvision1-mini series products use high-performance dual-hetrodyne transceivers

which, unlike poor performing direct conversion (zero-IF) receivers in the market, use RF mixing

stages, pre-selection, post-selection & IF filtering and real-time DSP to achieve high dynamic

range in a crowded electromagnetic environment.

• DTA-9590 ultra-wideband transceiver provides

0.5-18 GHz frequency range, instantaneous BW of

500 MHz, 12 bit data converters, DDC & DUC

based operating BW selection and baseband I &

Q data conversion.

• I&Q data for each channel is transferred over 2x

10 GbE networks (@1.6 Gbytes/s) for

record/playback and processing.

• Multiple DTA-9590 systems can be used with

independent tuning to increase the stare BW (e.g,

with 8 x DTA-9590 the stare BW can be 4 GHz) in

a high probability of intercept receiver or phase-

coherently for DF or beamforming applications.

Multi-Antenna RF Playback

User PC

DTA-3380 can be configured for any

number of transmit channels for either

phase-coherent or independently tuned

transmit operation. The tuning range is

20 MHz – 6 GHz and the maximum

operating BW is 80 MHz.

Pre-recorded or computer generated

data can played back out at user

selected RF frequencies. Baseband I &

Q data for each channel is first digitally

up converted by on-board DUC to

provide analog IF output for up

conversion to desired RF frequency.
