Abstract: The realization of a millimeter-wave time-delay module is proposed, and the module is fabricated and measured to validate the design method. For example, we have designed a Ka-band time-delay module integrating 7-bit delay and gain compensation. According to the measurements, amplitude fluctuation is better than ±1. 0 dB. Time-delay phase and amplitude accuracy achieve better than ±10° and ±1. 0 dB, respectively. Phase nonlinearity is within 20°, and voltage standing wave ratio (VSWR) is within 1. 8.
