【Abstract】 A study and development of high density integrated digital array module(DAM) is introduced in the paper. The block diagram of DAM is presented. Finally, the experimental results are presented. The noise figure, output power, amplitude-phase consistency of DAM are analyzed in detail. The experimental results show that the DAM has several advantages, such as low noise figure, high output power and high density integrated. The DAM can meet the needs of Phased array antenna radar. Finally, the photo of test charts are presented.更多还原
