Patent ID: 7684763

Claim:
A transceiver circuit, comprising: at least one transmission path having a local oscillator input coupled to a frequency conversion device of the transmission path; a first reception path having a local oscillator input coupled to a frequency conversion device of the first reception path; at least one second reception path having a second local oscillator input coupled to a frequency conversion device of the second reception path; at least one first, second and third local oscillator circuit configured to generate and output a respective frequency-tunable output signal; a programmable frequency divider circuit having at least three inputs and at least three outputs, wherein a respective input is coupled to a respective output signal of the at least first, second and third local oscillator circuits, and further comprising a first output coupled to the local oscillator input of the at least one transmission path, a second output coupled to the local oscillator input of the first reception path, and at least one third output coupled to the local oscillator input of the at least one second reception path, and wherein the frequency divider circuit is configured to divide a frequency of the respective output signal present at least one of the inputs with an adjustable divider ratio and output a frequency-divided signal at least one of the at least three outputs.
