This letter presents a simple and compact design approach for broadband analog phase shifters and its demonstration. An octave bandwidth can be obtained by alternately cascading low-pass filters (LPF) and high-pass filters (HPF) that importantly provide complementary phase-changing characteristics over ''frequencies.'' Achievable phase change per segment can be multiplied by cascading multiple segments that operate as independent phase shifters, thereby reaching 360 degrees of phase shift. We demonstrate one-and twosegment phase shifters consisting of cascaded LPF-HPF-LPF structures, of which capacitors in each filter are implemented by varactors, over a frequency range from 0.7 GHz to 1.4 GHz. Measurements show 65.8 degree average phase shifts from the single-segment and 128 degree from the double-segment, which is about twice as much as the singlesegment shifter's.

“…The high‐pass/low‐pass phase shifter was first proposed over 30 years ago, with a detailed analysis appearing shortly thereafter . This type of phase shifter had great appeal compared to conventional switched line, reflection and loaded line phase shifters, due its superior phase‐bandwidth capabilities .…”

linearly and circularly polarized rectangular dielectric resonator antennas, IEEE Trans Antennas Propag 60 (2012), 751-759. 13. S. Ahdi Rezaeieh and M. Kartal, A new triple band circularly polarized square slot antenna design with crooked t and f-shape strips for wireless applicationsABSTRACT: This article proposes a new type of GaN HEMT-based high power phase shifter operating at X-band. The design includes a 22.5 phase shift network and a high power SPDT switch. The design and resulting performance are discussed in detail and are confirmed by experimental and simulation results, which are in good agreement up to 20 GHz. The one bit phase shifter exhibits good phase performance, insertion loss, and return loss. The proposed phase shifter MMIC has been successfully demonstrated using a 0.5 lm gate GaN HEMT process.
