MEMS true-time delay circuit for broadband antennas
Published: Nov 13, 2002
Abstract
A monolithic true-time delay (TTD) circuit based on metal-contact RF MEMS microrelays has been successfully fabricated and characterized. The TTD circuit was designed to produce flat delay time over a DC-to-40 GHz bandwidth with full 360-degree phase control at 22.5-degree intervals at 10.8 GHz. Measurements show a close match to the designed delay times for all sixteen delay states with 2.2 to 2.6 dB of insertion loss at 10 GHz. The worst group...
