Abstract
A tool for use in a borehole in a geological formation may include a chassis, a drill collar surrounding the chassis, a port plug coupled between the drill collar and the chassis, RF antennas carried by the drill collar, and a multi-chip module (MCM) electronics package(s). The electronics package(s) may include a hermetically sealed electronics housing positioned between the chassis and the drill collar, a substrate within the electronics housing, RF transmitter circuitry on the substrate to cooperate with at least one first RF antenna to transmit RF signals into the geological formation, and RF receiver circuitry on the substrate to cooperate with at least one second RF antenna to receive RF signals from the geological formation. Furthermore, an electronics housing mount may couple the electronics housing with the port plug, and the electronics housing mount may have a passageway extending therethrough for receiving the port plug.
