Patent ID: 8385855

Claim:
A dual conversion transmitter, wherein the transmitter is configured to divide a first oscillator signal into a second oscillator signal and a third oscillator signal, wherein the transmitter is configured to perform frequency scaling such that the second and third oscillator signals have different frequencies from each other, the transmitter further comprising: a first mixer, wherein the first mixer is configured to utilize the second oscillator signal to facilitate frequency conversion; and a second mixer, wherein the second mixer is configured to utilize the third oscillator signal to facilitate frequency conversion; and a filter configured to filter the output of the first mixer and to provide the output of the filter to the input of the second mixer; wherein the transmit frequency conversion is the result of one of: (i) the sum of an intermediate frequency (“IF”) transmit signal frequency and the third oscillator signal frequency, and (ii) the difference of the IF transmit signal frequency and the third oscillator signal frequency.
