title = "A tunable group delay circuit for time delay matching applications in communication systems",
abstract = "In this paper, a reflective type tunable group delay circuit (TGDC) is proposed. The proposed TGDC consists of a 3 dB 90° hybrid coupler and reflective type resonators. The design equations of the proposed TGDC have been derived using port reduction method and validated by simulation and experimental results. In order to show the validity of the proposed TGDC, the simulation and an experiment were performed for a wideband code division multiple access (WCDMA) downlink band operating at 2.11∼2.17 GHz. According to the experiment, the group delay (GD) time variation of 3±0.17 ns over bandwidth of 60 MHz with an excellent flatness is obtained.",
