Abstract
A MMIC multi-port highly-integrated phase control device, suitable for application in low cost phased-array antennas is presented. The MMIC consists of eight LNAs, eight sets of RF-switches, a phase manifold, eight phase shifter networks for phase control and two 4 to 1 output power combiners. The DC power supply circuitry, the digital control circuitry and the RF sub modules are combined on the same die. The chip is designed in a mixed analog / digital 0.25 µm PHEMT technology. It is shown that the functionality of this chip is equivalent to eight separate 3-bit phase shifters.
