Product Description

The 17.7-21.2 GHz 45W K-Band 1024-Element Receiver Subarray is an advanced phased-array radar module designed for high-performance satellite communications (SATCOM), and radar systems. Operating in the K-band (a subset of millimeter-wave frequencies), this subarray delivers high power (45W), wide bandwidth (3.5 GHz), and precise beamforming capabilities, making it ideal for aerospace, and  wireless applications.

Product Features

1024-Element Active Electronically Scanned Array (AESA): Enables rapid beam steering without mechanical movement, critical for tracking fast-moving targets.

Digital Beamforming (DBF): Allows dynamic beam control for simultaneous multi-target tracking and interference mitigation.

Low Noise Figure (NF): Ensures high sensitivity in receiver mode for weak signal detection.
