1. An electronic device comprising:
a circulator, including a dielectric substrate having an aperture, a ferrite disc fit within the aperture in the dielectric substrate, the dielectric substrate and ferrite disc co-fired together to contain the ferrite disc within the aperture of the dielectric substrate, the circulator further including metallization;
an antenna;
a semiconductor transistor-based transmit amplifier, supported by the dielectric substrate, the circulator coupled between the transmit amplifier and the antenna; and
a semiconductor transistor-based receive amplifier, supported by the dielectric substrate, the circulator coupled between the antenna and the receive amplifier.
