Analog Devices’ Plug-and-Play Antenna Chip Simplifies Phased Array Radar for Avionics and Communications Equipment Designers
16 Maio 2018 - 9:00AM
Business Wire
Analog Devices, Inc. (ADI) today introduced a highly integrated,
active antenna beamforming chip that allows designers to quickly
replace bulky, mechanically steered antenna platforms with a
compact, solid-state solution for phased array radar and
communications systems. The ADAR1000 chip simplifies design and
significantly reduces the size, weight and power of phased array
radar systems for defense, surveillance, air traffic control,
communications and weather monitoring. For avionics designers, the
ADAR1000 enables flat-panel antenna arrays, which shrinks the
profile of conventional radar systems and facilitates the design of
smaller, lighter aircraft. The new ADAR1000 is a plug-and-play chip
that allows designers with little or no RF experience to extend the
performance and operating lifetime of their radar systems.

The 4-channel ADAR1000 active antenna beamforming chip replaces
12 discrete components needed for antenna phase-gain adjustments
and digital controls. The IC supports time division duplexing (TDD)
across the X and Ku bands. It includes an integrated T/R switch
that can be used to select the common port as an input for transmit
(Tx) or an output for receive (Rx). The four pairs of Tx and Rx
channels have independently programmable gain and phase settings.
The ADAR1000 can be configured to directly control all aspects of
external T/R module pulsing with minimal extra circuitry. All
settings can be loaded into built-in memory for fast access to
gain-phase states and T/R module settings. The ADAR1000 offers a
scalable building block for fast implementation of active antenna
phased arrays targeting next-generation radar and communications
systems without the need for extensive third-party design
support.
“ADI is combining the industry’s broadest RF portfolio with
extensive design and packaging expertise to help customers quickly
implement phased array antennas,” said John Cowles, general manager
of Analog Devices’ RF and Microwave Business Unit. “Our new phased
array offering is smaller, lighter, and as powerful as a typical
phased array solution. It also increases potential uses for phased
array as it significantly reduces the profile of the antenna.”
