1. Hardware Platform:
Digital IF FPGA Board: Two FPGAs together with Analog and digital convertors. The initial FPGA board with sample up/down to/from 140MHz IF. The FPGA will implement DDC, DUC, CFG, DPD, and AGC with DIF interface connectors.
RF Transceiver Board: Using third-party components, the RF transceiver will convert the IF to RF and visa versa.
RF Functional assemblies:
Variable Phase Shifter: A variable phase shifter that can control the beam-tilt in a base station antenna by +/- 10 degrees.
RF Multiplexer: A RF assembly that has one RF input and 4 RF outputs with control interface for ISM2400 networks.
Automatic Tuning Circuit: A reconfigurable tuning circuit that can tune the antenna resonance by +/- 5%.
RF Jammer: A RF assembly that can jam signals in the ISM2400 band and still follow OFTA specifications.
