This repository contains the hardware design for the RF over fiber transmitter module. This module provides the antenna-local analog signal processing post-LNA and drives the laser of the RF over fiber link. Additionally, this module provides several monitor and control points that will eventually be integrated into the telescope's global monitor and control system.
