10.0GHz to 14.5GHz 4 nodes TX MMIC Beamformer

The DM5001 is a SiGe BiCMOS die, purposely designed for accurate Phase shift and gain control of  beamforming antennas operating in the 10.0GHz to 14.5 GHz.
The MMIC die embeds a 1to 4 Wilkinson Power Splitter and 4 RF Arms with independent gain and phase shift controls.
The phase shifting range is 360 degrees at all operating frequencies, with a resolution of 5.625 degrees. (6 bit phase control).  The VGA control range is 16 dB with a linear in dB controlled by 5 bits (0.5dB step)
The BF RF Array coefficients (phase and gain) can be conveniently controlled via a standard serial SPI interface.
