Patent ID: 8670322

Claim:
A millimeter-wave radio frequency (RF) system, comprising: a single transmission line for connecting a first part of the RF system and a second part of the RF system, the single transmission line transfers a multiplexed signal between the first part and second part, wherein the multiplexed signal includes an intermediate frequency (IF) signal, a local oscillator (LO) signal, a control signal, and a power signal; the first part includes a baseband module and a chip-to-line interface module for interfacing between the baseband module and the single transmission line, wherein the chip-to-line interface module includes a multiplexer for multiplexing the IF signal, the LO signal, and the control signal and producing a first multiplexed signal; a bias-T coupled to the multiplexer for inserting the power signal to the first multiplexed signal to produce the multiplexed signal to be transferred over the single transmission line, wherein the bias-T is connected to the single transmission line, wherein the multiplexer includes a high-pass filter (HPF) for passing signals at an IF frequency band of the IF signal; a base-pass filter (BPS) for passing signals at a LO frequency band of the LO signal; and a low-pass filter (LPF) for passing a signal at a control frequency band of the control signal, wherein the IF frequency band, the LO frequency band, and the control frequency band are set according to a frequency plan, wherein the multiplexer further de-multiplexes the IF signal, the LO signal and a control signal received from the RF module over the single transmission line; and the second part includes a RF module and a line-to-chip interface module for interfacing between the RF module and the single transmission line, wherein the first part and the second part are located away from each other.
