We investigate the impact of photodetector (PD) aperture size and wire bond length on the performance of analog radio over multi-mode fiber (A-RoMMF) systems using high-frequency bands up to 28GHz. It is realized that transmission characteristics of A-RoMMF is affected by the change of frequency response due to the PD aperture size and the bonding wire length. We also demonstrate A-RoMMF transmission using an optical receiver mounted PD and a low noise amplifier (LNA) on one printed circuit board (PCB) to improve size, link gain, and transmission characteristics.
