A design method for dual-band Class III loaded-line phase shifters is presented. The center line and the loads of the phase shifter are designed to meet dual-band requirements. Two single-pole-double-throw switches are used to switch between two reactive loads in the two phase states. Four possible reactive loads are considered and closed-form formulas are provided to achieve dual-band operation....
A new switched 180?? phase shifter with a small phase error over a large bandwidth using lumped elements is proposed. The topology has two states, an all-pass network (APN) as the reference state, and a bandpass filter (BPF) as the phase shifting state. In the BPF, LC resonators are used to change the slope of the insertion phase to achieve a good phase alignment between the two states for a large...
The 90degphase bit of high-pass/low-pass phase shifter suffers from large phase error compared to the smaller phase bits. To improve the phase error performance, this work develops a network that provides a differential phase of 90degwith a small phase error (< plusmn2deg) over a large bandwidth. Compared to other work focused on this bit, the new network shows theoretical bandwidth of 88% (2.6:1)...
