The MAX2880EVKIT will output frequencies in the range of 5.84GHz to 6.04GHz. Although the MAX2880 device can output up to 12.4GHz, the MAX2880EVKIT output frequency range is limited by the voltage controller oscillator (VCO), which is external to the MAX2880 device. It is not possible to achieve frequencies above 6.04GHz using the MAX2880EVKIT without redesigning the board for a new VCO.
