Product Features

Environmental

Operating Ambient: -30 to +70°C.

Assumes Plank Fluid Inlet Temperature is in the range +10 °C to +48 °C

Storage: -40 to +85°C

MTBF : TBD

NOTES

(1) Limited by circulator specification and physical dimensions of the QTRM

(2) Up to 3dB reduction in useable attenuation range due to Calibration.

(3) Figure given for Ref Attenuator state, Ref Phase State and includes Beam former losses.

(4) N.F. given for Ref Attenuator state, Ref Phase State and includes Beam former losses.

(5) Dimension “D” is for Demo Unit only. Potential to reduce to 14.1mm for a practical AESA

configuration. See outline diagram in section 8 below.

•

RS485 Half-Duplex, 5.0 Mbps serial data bus for control and monitoring.

•

Plank operating current and power supply health monitored and reported on request along

with health status of each QTRM

•

Automatic shut-down of individual QTRM’s if their internal temperature reaches a critical limit

where damage could occur. Hysteresis applies.

•

Positive supplies inhibited (with the exception of the digital control circuits) if negative supply

is lost

•

Direction cosines used for beam steering

•

QTRM’s respond to individual address or broadcast messages.

•

Module position assignment

•

Sequenced QTRM power-up timing based on module position address

•

Ability to schedule up to 16 phase & amplitude settings for rapid beam switching

•

Ability to disable internal modulation and apply externally

•

Array CAL allows end-user to add additional TRU phase & amplitude calibration.

•

Read-back of CAL phase & amplitude values for each TRU.

•

Selection of internal/external Clock source to allow synchronisation of multiple QTRM’s.
