Integrated radio receiver/transmitter structure

Claim 1

An integrated radio receiver/transmitter structure, comprising: a first dielectric substrate having first and second opposed surfaces, the first dielectric substrate having a ground plane on the first surface and a conductive resonator on the second surface, the conductive resonator having first and second terminals; a second dielectric substrate having first and second opposed surfaces, the second dielectric substrate having a ground plane on the first surface, the second surfaces of both dielectric substrates being attached to each other, the first and second dielectric substrates forming a bandpass filter; and a single integrated circuit chip transmitter/receiver section attached to the second surface of the first dielectric substrate, the single chip transmitter/receiver section comprising: an antenna switch having an antenna port, a receive signal output port and a transmit signal input port, the antenna port is coupled to the second terminal of the conductive resonator; an amplifier having an input and output terminal, the amplifier input terminal being coupled to the antenna switch receive signal output port; a first mixer means having first and second input terminals and an output terminal, the amplifier output terminal being coupled to the first input terminal of the first mixer means; a second mixer means having first and second input terminals and an output terminal, the second input terminals of the first and second mixer means being coupled together for receiving a first reference signal; and a power amplifier having an input and output port the input port of the power amplifier is coupled to the output terminal of the second mixer means and the output port of the power amplifier being coupled to the transmit signal input port of the antenna switch.
