Plank

The Plank is the quick-remove host for four QTRMs, creating

a 16-channel assembly with integrated antenna. The plank

incorporates the RF manifold, DC distribution and logic/control

distribution and is inserted into the AAAU as a rack-mounted

sub-assembly.

Cooling Solutions

APITech has a range of cooling solutions to support dierent

platform applications that can be implemented at QTRM or at plank

level.

AAAU

APITech’s steerable AAAU easily bolts on to the SPU for use in air,

sea, and ground-based AESA radar, data link, and satcom

applications. Both the unit’s compact size and scalability allow for

use across multiple defense and commercial aerospace programs.

The AAAU is comprised of multiple, easy-to-replace planks, which

form a sub-array.

Featured Active Antenna

Array Applications

AESA is a exible technology platform that is capable of

simultaneous, multi-target tracking. Military organizations have

embraced AESA radar for use on defense aviation, ground and

maritime platforms, missile defense programs, as well as in support

of critical satcom systems.

Radar

APITech’s AAAU concept is suitable for multi-function radar

systems for naval, air and land defense applications, delivering

surveillance, tracking, guidance, and communications. In the

civilian aerospace markets, the AAAU concept is ideal for air

trac control radar.

Data Links

The AAAU is equally applicable to data link solutions for tactical

command and control, enabling surveillance, tracking, guidance,

and communication.

Satcom

AESA enables tactical communication via satellite. APITech’s

AAAU can deliver electronic steering/tracking of the satellite,

and can be congured as a low prole antenna or as a conformal

antenna for xed wing aircraft.

Active Antenna Array Units

Modular Units Featuring Line-Replaceable Quad T/R Module ‘Common

Building Blocks’ for Scalability and Ease of Integration and Repair

Using a Line Replaceable Unit (LRU) approach, APITech has

developed a solution set that streamlines system integration,

simplies repair, and reduces the cost of ownership of AESA,

E-Scan, and other next-generation radar platforms.

APITech’s Active Antenna Array Unit (AAAU) system is comprised

of multiple QTRM (Quad Transmit Receive Module) assemblies,

packaged in removable planks that form the AAAU sub-array.

The QTRMs are Line Replaceable Units (LRU), which allow for ease

of assembly and maintenance.

These APITech-designed and manufactured QTRMs are ready to

use out of the box. All that is necessary is the upload of system

calibration data, which then propagates through the system,

speeding set-up time.

Quad T/R Modules

Common Building Blocks for E-Scan & AESA Radar System Solutions.

APITech's Quad Transmit Receive Module, or QTRM, solutions for

AESA/E-Scan radar applications oer a unique and innovative

solution to system integrators and prime contractors seeking a

high performance, high level transmit/receive solution for the

development of active antenna array systems and sub-systems

This common module approach, which uses APITech’s European

designed and manufactured elements and COTS components,

delivers ease of system integration, rst line repair and reduced cost.

QTRM

Each Quad Transmit Receive Module (QTRM) includes full RF,

DC, control functionality (logic interface), calibration and BITE

status for each TRM, thermal and current overload protection,

as well as receive and transmit functions. Each eld-replaceable

QTRM common module is factory calibrated. The only set-up

needed is a one-time laptop upload of antenna osets.

Benefits & Features of

APITech’s Active Antenna

Array Solutions

Field Upgradeable

The solution elements are fully interchangeable, allowing for

ease of integration and fast repair. This is in contrast to current

Active Electronic Scanned Array (AESA) solutions, which require

the entire platform to be sent back for repairs and upgrades.

Simplified Installation

No calibration is required. Factory-Calibrated transmit/receive

modules are included with the solution, so only antenna osets

need to be uploaded. This signicantly speeds time to deployment.

Self-Monitoring Options

The solution oers cooling options to support a variety of

platform applications. The unit self-monitors temperature and

engages automatic shut down if the internal temperature

reaches a critical limit.
