true-time delayAn Opto-VLSI-based (VLSI: very-large-scale-integration) tunable true-time delay (TTD) generation unit used for adaptive null steering in phased array antennas is presented. The system is based on continuous tunable optical TTD technique. Arbitrary multiple true-time delays to ...
A radio frequency microelectromechanical system (RF MEMS)-based true-time-delay (TTD) phase shifter is one of the key components in a modern electronically steerable phased array for satellite communication, radar systems, and high precision instrumentation. The phase shifter controls the signal phase...

In this paper, we propose the design of switched line True time delay (TTD) using cascaded switches, which removes off-switch resonance. Conventional switched lines with two different delay-time difference, 15ps and 270p, are presented to indicate that off-switch resonances can be observed in ...
