Abstract
A system for transmitting or receiving signals may include an integrated circuit (IC), a transducer operatively coupled to the IC for converting between electrical signals and electromagnetic signals; and insulating material that fixes the locations of the transducer and IC in spaced relationship relative to each other. The system may further include a lead frame providing external connections to conductors on the IC. An electromagnetic-energy directing assembly may be mounted relative to the transducer for directing electromagnetic energy in a region including the transducer and in a direction away from the IC. The directing assembly may include the lead frame, a printed circuit board ground plane, or external conductive elements spaced from the transducer. In a receiver, a signal-detector circuit may be responsive to a monitor signal representative of a received first radio-frequency electrical signal for generating a control signal that enables or disables an output from the receiver.
