Abstract

A wireless transceiver using a phased array antenna panel for producing multiple beams includes receive antennas forming a receive configuration and transmit antennas forming a transmit configuration. The receive antennas form a plurality of receive beams and the transmit antennas form a plurality of transmits beams, based on phase and amplitude information provided by a master chip in the phased array antenna panel. The receive and transmit configurations can include sub-configurations, each sub-configuration forming one of the plurality of receive beams or one of the plurality of transmit beams. At least one receive antenna and at least one transmit antenna can be connected to a corresponding plurality of receive phase shifters and a corresponding plurality of transmit phase shifters respectively. The wireless transceiver can form a relay transmit beam based on a receive beam provided by a hardwire connection.

First claim

The invention claimed is:

1. A wireless transceiver, comprising:
a phased array antenna panel configured to produce multiple receive beams and multiple transmit beams;
receive antennas configured to form a receive configuration; and transmit antennas configured to form a transmit configuration,
wherein said receive antennas are configured to form a plurality of receive beams based on receive phase information and receive amplitude information,
wherein said receive phase information and said receive amplitude information are provided by a master chip in said phased array antenna panel,
wherein said transmit antennas are configured to form a plurality of transmit beams based on transmit phase information and transmit amplitude information;
wherein said transmit phase information and said transmit amplitude information are provided by said master chip in said phased array antenna panel,
wherein said receive configuration comprises a plurality of receive sub-configurations, each of said plurality of receive sub-configurations forms at least one of said plurality of receive beams,
wherein said transmit configuration comprises a plurality of transmit sub-configurations, each of said plurality of transmit sub-configurations forms at least one of said plurality of transmit beams, and
wherein said receive phase information, said receive amplitude information, said transmit phase information and said transmit amplitude information are provided by RF front end chips that are connected to said master chip.

2. The wireless transceiver of claim 1 , further comprising at least one dummy antenna between said receive configuration and said transmit configuration, and
wherein said at least one dummy antenna is coupled to a terminating resistor.

3. The wireless transceiver of claim 1 , wherein said wireless transceiver is configured to operate in a frequency range of between 27.5 GHz and 29.5 GHz.

4. The wireless transceiver of claim 1 , wherein said wireless transceiver is configured to dynamically assign reconfigurable receive and transmit antennas to increase at least one of a number of said transmit antennas or a number of said receive antennas.
