In this paper, an amplitude tunable two-tone digital phase shifter is designed, fabricated, and measured. This phase shifter has 16 channels and every channel is able to output arbitrary amplitude below 0 dBm and arbitrary phase among 360°. The two-tone output frequencies are 810 MHz and 4.5 GHz which are possibly used in 5G as phase changeable local oscillator (LO) frequency for up conversion to...
