Analog Devices Unveils Direct Conversion Receiver Development Platform for Radar Systems
10 Dicembre 2014 - 2:00PM
Business Wire
AD-FMCOMMS6-EBZ supports key L- and S-band
frequency radar bands.
Analog Devices, Inc. (NASDAQ: ADI) announced today an integrated
direct conversion receiver development platform for radar systems
where reduced size, weight and power (SWaP) implementation is
critical. The new AD-FMCOMMS6-EBZ platform is a 400-MHz to 4.4-GHz
receiver (1350 MHz to 1650 MHz with installed filters) supporting
the key L- and S-band frequency radar bands. The platform’s
VITA57-compliant form factor ensures seamless connectivity to FMC
(FPGA mezzanine card) platforms. The AD-FMCOMMS6-EBZ is suitable
for defense, communications, and instrumentation radar systems
requiring a high level of integration and performance delivered in
a compact footprint. These include early warning detection, weather
surveillance, and air traffic control systems.

The AD-FMCOMMS6-EBZ receiver platform integrates the AD9652 dual
16-bit A/D converter, ADL5566 high-dynamic-range RF/IF dual
differential amplifier, and ADL5380 quadrature demodulator, all of
which are COTS (commercial-off-the-shelf) components. A complete
design support package is available for the AD-FMCOMMS6-EBZ, and
includes schematics, layout files, noise analysis worksheet, FPGA
HDL (hardware description language) code, and software drivers.
About the AD-FMCOMMS6-EBZ Receiver Development
PlatformThe AD-FMCOMMS6-EBZ utilizes an I/Q demodulator to
implement a direct conversion or zero IF architecture in which just
one frequency translation is required, compared to a
super-heterodyne receiver that must perform several frequency
translations. A single frequency translation is advantageous
because it reduces receiver complexity and the number of conversion
stages needed, which in turn increases performance and reduces
power consumption. The architecture also avoids image rejection
issues and unwanted mixing by adding an amplification stage to
maintain the full-scale input to the A/D converter. In addition,
the image rejection inherent to the I/Q modulation scheme removes
the need for an expensive anti-aliasing filter. The on-board local
oscillator and converter clock share the same reference signal to
prevent smearing.
The AD-FMCOMMS6-EBZ receiver development platform incorporates a
full direct-receive signal chain path and has a bandwidth of 220
MHz with a pass-band flatness of +/- 1.0 dB. The RF input range of
the ADL5380 demodulator is 400 MHz to 6 GHz and is powered by a
single 5-V supply. The ADL5566 4.5-GHz dual differential amplifier
is optimized for IF and dc applications and provides a gain of 16
dB. The AD9652 dual 16-bit, 310-MSPS A/D converter achieves the
industry’s lowest noise at the highest speed; this level of
performance enables target identification at a much longer range.
The SNR and SFDR measured at an IF of 145 MHz are 64 dB and 78 dBc,
respectively. Additional on-board functionality includes power
management and clock distribution with fanout.
