Patent ID: 7146136

Claim:
A MMIC-based E-Band transceiver front-end comprising: a first MMIC device comprising, a transmission circuit for receiving a data stream input at a baseband frequency, mixing the data stream with an LO signal having an E-Band frequency, and transmitting a resultant data stream at an upconverted E-Band frequency; a receiver circuit for receiving a data stream having an E-Band frequency, mixing the received data stream with an LO signal having an E-Band frequency, and downconverting the resultant mixed received signal to an intermediate frequency (IF); and an LO signal circuit for dividing a received LO signal at an E-Band frequency and communicating the LO signal to said transmission and receiver circuits; a second MMIC device comprising a multiplier circuit for receiving an LO signal at a reference frequency, and multiplying the LO signal to an E-Band frequency; a third MMIC device comprising, a second downconversion circuit for mixing the mixed received IF signal with an LO signal, and downconverting the resultant mixed received signal to a baseband frequency, and an LO generation circuit for generating an LO signal, communicating the LO signal to said second MMIC device, coupling the LO signal, dividing the coupled LO signal, and communicating the divided LO signal to the second downconversion circuit.
