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.

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.
