Patent ID: 8170497

Claim:
An integrated circuit (IC) comprises: a plurality of circuit modules on a die; a package substrate supporting the die, wherein the package substrate includes a micro-electromechanical (MEM) area; a radio frequency (RF) bus transceiver module on the die and associated with at least one of the plurality of circuit modules that operates in a 60 GHz frequency band, wherein the RF bus transceiver module includes: a baseband processing module coupled to convert outbound bus data into an outbound bus symbol stream and to convert an inbound bus symbol stream into inbound bus data; a transmitter section coupled to convert the outbound bus symbol stream into an outbound RF bus signal that is transmitted via a waveguide within the package substrate; a receiver section coupled to convert an inbound RF bus signal that is transmitted via the waveguide within the package substrate into an inbound bus symbol stream; a transformer having a differential winding and a single-ended winding, wherein the differential winding is coupled to at least one of the transmitter section and the receiver section; an impedance matching circuit coupled to the single-ended winding; and a transmission line coupled to the impedance matching circuit, wherein at least one of the transformer, the impedance matching circuit, and the transmission line is within the MEM area.
