Beam Squint Compensator

Technical Explanation

When an antenna array uses phase shifters across ultra-wide bandwidths (e.g., a 10 GHz wide channel at 150 GHz), the physical angle of the beam shifts across the frequency band—a distortion known as 'beam squint'. At the edge frequencies of the band, the beam misses the target completely. True Time Delay (TTD) Beam Squint Compensators replace simple phase shifters with true time delay elements, ensuring the beam points in the exact same spatial direction across every frequency in the ultra-wide channel.

Key Functions

• Eliminating spatial beam squint distortion across massive multi-gigahertz channels
• Ensuring consistent spatial beam pointing direction from carrier bottom to top frequencies
• Replacing frequency-dependent phase shifters with True Time Delay (TTD) analog/photonic lines
• Preventing severe signal-to-noise ratio degradation at the edges of Sub-THz bands
• Enabling full utilization of 10-30 GHz continuous bandwidth pipes in commercial base stations
