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