This paper presents a two-way vector modulator integrated circuit aimed for millimeter wave phased array systems. The active vector modulator is based on the Cartesian topology. Phase can be tuned continuously 360 degrees and the usable gain control range is more than 10 dB. The chip includes a low-noise preamplifier and a buffer amplifier in both receive and transmit paths, which are coupled together...
To improve the performance of -band equipment for humidity sounding of the atmosphere, a high-gain and low-noise amplifier is needed. Here, the performances of 165 and 183 GHz low-noise amplifier microchips intended for atmospheric water vapor profiling application are reported. The microchips are manufactured in metamorphic high-electron mobility transistor technology having a gate length of 50...
