Abstract
Based on a 0.15 μm GaAs pseudomorphic high electron mobility transistor(pHEMT)process,a multifunctional monolithic microwave integrated circuit(MMIC)for ultra-wideband receiver amplitude-phase is developed,operating at a frequency of 2-12 GHz.The chip integrates a low noise amplifier,digitally controlled attenuator,digitally controlled phase shifter,switches,13-bit serial digital circuit and power modulation circuit,with a compact size of 4.80 mm ×4.35 mm.The MMIC exhibits high phase-shifting accuracy,low noise figure and low power consumption across the ultra-wideband range.Measurement results demonstrate that from 2 GHz to 12 GHz,the small signal gain of the MMIC is above 29 dB and the noise figure is below 2.5 dB.The root mean square(RMS)phase error and RMS attenuation error are below 3° and 0.35 dB.The total power consumption is 0.37 W.关键词
