Abstract

The Radio Neutrino Observatory in Greenland (RNO-G) seeks to detect the Askaryan
radio emission from energetic neutrinos (> 10 PeV) interacting in the Greenland
ice sheet. The RNO-G detector comprises an array of independent and autonomous
radio-detector stations, each with a hybrid design composed of deep borehole (

$\sim$ 100m) and
surface antennas, which require low-power, robust, and scalable low-noise radiofrequency (RF) amplifier and signal-transport systems over a

$\sim$ 80-650MHz bandwidth. In this contribution, we will present the design and performance
of the custom RNO-G RF signal chains, including a field-proven and low-cost RF-over-fiber (RFoF) unit.
