Patent ID: 8139625

Claim:
A system-on-chip (SOC) transceiver configured to operate in excess of 100 GHz, the transceiver comprising: a quadrature oscillator configured to generate a fundamental frequency and a second harmonic frequency and comprising at least a pair of high frequency outputs at said second harmonic frequency, wherein at least the second harmonic frequency exceeds 100 GHz; a transmission output coupled to one of the high frequency outputs for transmitting an output signal at said second harmonic frequency; a transmission signal transformer coupled to the other one of the high frequency outputs, the transmission signal transformer configured to generate a differential oscillator signal at the second harmonic frequency; a radio frequency input for receiving radio frequency signals at the transceiver from an antenna; a radio frequency signal transformer coupled to the radio frequency input, the radio frequency transformer configured to generate a differential radio frequency signal at the radio frequency; a mixer configured to compare the differential radio frequency signal with the differential oscillator signal and output the comparison as an intermediate frequency signal.
