Mixed signal high integration MMIC phase control device for application in phased-arrays
conference paper
A MMIC multi-port highly-íntegrated phase control device, suitable for applícation in low cosl phased-array antennas is presented. The MMIC consists of eìght 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 cìrcuitry, the dígítal control circuítry and the RF sub modules are combined on the same die. The chìp ís designed in a mixed analog / digítal 0.25 um PHEMT technology. It ìs shown that the functíonality of this chip ìs equivalent to eight separate 3-bit phase shìfters.
