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.
Hardware
Designed using KiCad 9, and requires setup of our library.

Questions
How big is the Ftx PCB?
It measures 60 × 40 mm and has 4 copper layers, 1.56 mm thick.
What parts does the Ftx use?
153 parts, built around the PGA-105+, PAT1220-C-3DB-T5, AD8363ACPZ-R7 and F1958NBGK. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ftx KiCad files?
From the SETIatHCRO/Front-Page repository on GitHub, at the commit this page was made from: the board is Analog-Signal-Components/RFoF/RFoF-Modules/RFoF-TX/ftx.kicad_pcb and its schematic Analog-Signal-Components/PAX/PAM-2025/PAM-modules/amplifier-module/amplifier-module-v2/Altium/amp_v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ftx design in my own project?
Its repository states no licence, so its author keeps all rights: ask SETIatHCRO before reusing the design.
