This document outlines the design of an outdoor polyphase filter bank equipped with RFI calibration and synchronization handling features. It includes details about a two-channel (Tx/Rx) system operating from 70 to 450 MHz that utilizes a 2x730mW A/D conversion strategy. The system emphasizes effective handling of reduction boxes for word processing, local pre-processing of RFI signals, and includes provisions for a fast digital link for data transmission. Power supply options include small solar panels for outdoor deployment.
