“…Electronically reconfigurable phase shifters (PSs) are a key element in the design of phased arrays. The different typologies of PS can be grouped into two main categories: analog and digital PS. Analog PSs provide a continuously variable phase delay while in digital architectures the insertion phase can be only set to a fixed number of values.…”

“…Ideally, the relationship between the analogue control voltage VnormalBBI/VnormalBBQ (short for VnormalBBI and VnormalBBQ) and the corresponding transmission phase and amplitude characteristic (S21) of a Cartesian type VM is as follows [29]:right leftthickmathspace.5emS21VnormalBBI2+VnormalBBQ2S21=arctanVBBQVBBI By using (1), we can calculate the corresponding VnormalBBI/VnormalBBQ of the desired S21, and use this pair of control voltages to set the VM. By comparing the measured S21 of the actual VM to the desired S21, we find that the amount of deviation between them is not significant in most cases.…”

“…When compared to passive phase shifter topologies, active phase shifter topologies such as vector-sum architectures, sometimes referred as vector-modulators provide better phase quantization levels in smaller chip sizes [8]- [10]. Unlike the passive phase shifter topologies, increasing the phase quantization levels in the vector-sum phase shifters (VSPS) do not increase the overall chip size but only increases the complexity of the digital control circuitry [11]- [14].…”
