The True‑Time Delay MMIC is an RF monolithic microwave integrated circuit based on GaAs pHEMT process. It precisely adjusts the propagation delay of RF signals via digital control, with tuning resolution at picosecond (ps) level.
Unlike digital phase shifters that only modify signal phase, true-time delay chips introduce physical time delay to RF signals to mitigate beam squint in wideband array systems and support stable beam scanning over broad bandwidth. The chip is available in bare-die form for chip-and-wire assembly, facilitating miniaturized integration of T/R modules with wide operating temperature range. It is suitable for wideband phased arrays, satellite communications, RF simulation testing and broadband wireless communication systems.
