A 26-32-GHz Dual-Polarization Receiver Front-End With Rapid-Response Mixed-Signal Polarization Alignment for Ultrareliable Low-Latency Communications

This work presents a 26-32-GHz dual-polarization receiver (RX) with a novel autonomous polarization alignment technique in the front-end. The system employs an mm-Wave dual-polarization RX front-end with an IF analog/mixed-signal computation unit to achieve fast dual-polarization misalignment correction with no digital backend computation for mobile, dynamic, and ultrareliable low-latency communications (URLLCs). It is implemented in the GlobalFoundries 45RFSOI CMOS process occupying 5.67 mm(2) total area. It has a wideband S-11 response from 25.5 to 34.5 GHz and achieves an ultrarapid mu-second polarization mismatch correction time. Polarization leakage suppression of up to 35 dB is measured with the RX gain of 28 dB and NF of 5.8 dB.

Automated summary

This work proposes a 26-32-GHz dual-polarization receiver with autonomous polarization alignment technique, ideal for mobile, dynamic, and ultrareliable low-latency communications. The system achieves up to 35 dB of polarization leakage suppression and ultrarapid mu-second polarization mismatch correction time in experiments.
