Abstract
An ultra-high-bandwidth low-power-consumption wireless communication system includes (i) a Radio Frequency Integrated Circuit (RFIC) comprising a radio transmitter, transmitting millimeter-wave signals. The radio transmitter includes a Power Amplifier (PA) outputting the millimeter-wave signals at a low power level of between −10 dBm and 20 dBm, and by that allowing inclusion of the PA in the RFIC. The radio transmitter further includes a Voltage Controlled Oscillator (VCO) and a synthesizer driving a mixer up-converting signals into the millimeter-wave signals. The VCO and synthesizer have a combined phase noise between a first level and a second level, wherein the first level is high enough to allow inclusion of the VCO and synthesizer in the RFIC, and the second level is low enough to facilitate transmitting at 16-levels Quadrature-Amplitude-Modulation (16QAM).
