A highly integrated wideband millimeter wave MMIC converter using0.25 μm p-HEMT technology

摘要

A highly integrated wideband converter was designed to upconvertthe entire 6-18-GHz input RF frequency band to a 22-GHz intermediatefrequency using a 28-40-GHz local oscillator. The circuit was designedusing 0.25-μm pseudomorphic HEMT (high-electron-mobility transistor)technology. The converter incorporates a three-stage RF amplifier, athree-stage LO (local oscillator) amplifier, and an active balancedmixer, all integrated on a single chip 2440×2440 μm in size
