Abstract
A transceiver having a transmitting antenna, a receiving antenna, and a substrate having transmitter and receiver dies is disclosed. The transmitter generates an RF signal having a carrier frequency and the receiver detects and amplifies signals of the carrier frequency. The transmitting antenna and/or the receiving antenna includes a first wire antenna loop having a length greater than or equal to one tenth of a wavelength of the carrier frequency. The first wire antenna loop is connected to the transmitter die by a wire bond on a bond pad of the transmitter die. The antenna loop or loops can be encapsulated in an insulating material to protect the loops and fix the loops in space. The transceiver can be configured to operate as a galvanic isolator or a proximity detector.
