Glossary

TR Module: Transmit/Receive module — the core active component of a phased array, containing amplifiers, phase shifters, and switches for each element.

EIRP: Effective Isotropic Radiated Power — the power transmitted by an isotropic antenna to produce the same signal strength.

G/T: Figure of Merit — ratio of antenna gain to system noise temperature, indicating receive performance.

LHCP / RHCP: Left-Hand / Right-Hand Circular Polarization.

Liquid-cooled Micro-channel: A thermal management design using micro-scale fluid channels integrated into TR modules for high-power dissipation.

Modular Design: Architecture allowing individual subarrays to be replaced, upgraded, or reconfigured independently.

Composite Array: Multiple subarrays combined to form a larger aperture with enhanced performance.

SMA: SubMiniature version A — a co
