The TGP2108-SM from Qorvo is a 6-bit digital phase shifter that operates from 2.5 to 4 GHz while providing 360 of phase coverage with a LSB of 5.625. The phase shifter has an exceptional RMS phase error of < 20 and amplitude error of < 0.4 dB over most of the operational band. This high level of performance makes it ideal for S-band phased array applications. It is available in a small 5 x 5 mm plastic over mold QFN package, DC blocked on both ports with bi-directional operation and the use of positive only control logic. Low DC power consumption also provides the system designer more flexibility in the overall power management of the system.
