Abstract

A fabricated multilayer low-temperature co-fired ceramic (LTCC) delay line (approximate 16λ_g 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.
