Part Number: CC1101

Hi,
do we have any experience or reference designs in phased arrays, MIMO applications in sub-1GHz? This was a question from my customer.

Regards, Holger

    Hi Holger,

    I am not aware of previous work/designs for this application - I will ask the rest of the team to make sure.

    Regards,

    Zack

    Hi,

    Phased array applications for sub-1 is not too practical due to the physical size of the quarter wave especially for consumer wireless devices. This practice is much more used in the higher frequencies when the quarter wave is much smaller in size. 

    It is fully possible to phase array antennas for sub-1 GHz. Take the base station cell mobile antennas at 800/900 MHz for example but these are typically around 1 m in length with multiple dipoles connected inside and employ beam forming via the phase array.
