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")

In 2378, The Doctor, disguised as Captain Kathryn Janeway, sent a message from the Delta Flyer II to the USS Voyager through the ship's transceiver array, which was received by Ensign Harry Kim. (VOY: "Renaissance Man")
