A 6-bit digital-controlled attenuator with low phase imbalance for a K-band phased array system is presented in this paper. To decrease the insertion phase difference, the proposed design adopts a phase correction capacitor in the shunt branch of the conventional switched T/Pi structure. The capacitor and the parallel resistor compose a phase compensation network to correct the insertion phase error...
Available bandwidth (AB) measurement technologies have been widely applied in evaluating the efficiency of the network communication. The performance of most existing AB measurement methods relies on the quality of the input data, which inevitably contains noises during the measurement. These noises can be multisourcing from end-to-end packet transmission and measuring, and in many practical situations,...
