The RI 3041 from Ranatec is a 4x4 Butler Matrix that operates from 2.4 to 8 GHz. It can be used to control a beamforming network by switching the direction of beams to the desired beam port. In transmit mode, it delivers the full power of the transmitter to the beam, and in receive mode, it collects the signal from each of the beam directions with the full gain of the antenna array. The matrix supports multichannel MIMO testing for 4x4 antenna ports covering the conventional Bluetooth and Wi-Fi bands. It can also be used for antenna array beamforming and interface testing for multiple systems in the frequency range, and multichannel multipath emulation.
The RI 3041 can handle an input power of up to 5 W, provides an isolation of more than 13 dB, and has an insertion loss of less than 8 dB. It has an amplitude deviation of ±3 dB and a phase deviation of ±10°. This butler matrix is available in a module that measures 70 x 86 x 19 mm with SMA-female connectors.
