A controllable reflection type phase shifter that includes an adjustable hybrid coupler and controllable adjustable reflection load circuit is described and used in some embodiments to implemented a communication system. In some embodiments the communication system supports beam forming through the use of a plurality of TX/RX signal processing chains (SPCs), each SPC including at least one reflection type phase shifter, e.g., a controllable reflection type phase shifter. The controllable reflection type phase shifters in different SPCs of the array are configured, e.g., differently, based on the particular beam pattern being used to transmit or receive signals at a given time. Control information, e.g., control values, are stored in memory with the control values corresponding to an antenna pattern to be used at a given time being retrieved from memory and to control the circuits, e.g., controllable reflection type phase shifters, in the system.
