Wide Band Switched Delay Line using MEMS
Switches.
Proceedings of the 17th Research Colloquium on Communications and Radio Science into the 21st Century.
Abstract
This paper presents a high precision wide
band switched delay line with fine tuning capability and
low insertion loss. The circuit is designed to operate in
the frequency range from 1 GHz to 5 GHz and tuned
using MEMS switches targeting a minimum delay step
of 7 ps. The delay line uses a single layer of a high
permittivity substrate ("r =10), and the MEMS devices
are interconnected using conventional coplanar waveguide
technology (CPW). The circuit was designed and simulated
using CST Microwave Studio. The simulated group delay
shows a small deviation from the linear phase of less than
1o over a wide bandwidth compared to the performance of
SAW and ceramic filters [1]. The simulation results shows
an insertion loss and a return loss of better than 1 dB and
20 dB respectively.
