A transceiver array was a technology used in the subspace communication systems of various vessels in the 24th century. In 2373, Quark and Odo were forced to crash land on an unnamed Class L planet in the runabout USS Rio Grande. They removed the transceiver array from the crashed runabout and hauled it to the top of a nearby mountain to transmit a distress call through the planet's atmosphere. (DS9: "The Ascent")
