Abstract

A fabricated multilayer low-temperature co-fired ceramic (LTCC) delay line (approximate 16λg at 9.5 GHz), using 3D meander strip line, is proposed in this paper for the first time. The advanced quasi coaxial ground vias (QCOX-GND vias) are proposed for signal vertical interconnections in this multilayer structure. These technologies obtain good performances in the whole band (9~10 GHz). Measurement results show that, besides low insertion loss and low VSWRs, low time dispersion can be achieved as ≤±0.002 ns, which is very important to a delay line. The more compact size, as 8 mm × 10 mm × 2.37 mm, can also be obtained than other delay line structures.
