Abstract
According to one embodiment, an RF frontend IC device includes a first RF transceiver to transmit and receive RF signals within a first frequency band and a second RF transceiver to transmit and receive RF signals within a second frequency band that is different than the first frequency band. The RF frontend IC device further includes a converter and a multi-band local oscillator (LO) generator to provide LO signals to the converter. The multi-band LO generator includes a phase-lock loop (PLL) circuit operating at a PLL operating frequency, wherein the PLL operating frequency is outside of the first frequency band and the second frequency band. The multi-band LO generator also includes multiple frequency multipliers coupled to the PLL circuit to upscale the PLL operating frequency and to generate an LO signal having a frequency within a predetermined proximity from the frequency band.
