An X-band core chip is designed and fabricated in 0.18- CMOS technology, which can significantly reduce the monolithic microwave integrated circuit count required for realizing an active beam-former T/R module. The core chip consists of two RX/TX paths, each of which includes a 6-b phase shifter, a 6-b attenuator, along with two input and output amplifiers.(More)
Defense is an integrated concept, which includes both active and passive defenses. The effects of the war include heavy human and material losses and damages to cities that can be reduced by using passive defense measures and methods before the outbreak of the war. Metro (subway) trains, as one of the critical infrastructures, with a dual function can be(More)
