Abstract :
Two 30-GHz-band monolithic microwave integrated circuit (MMIC) receiver modules needed to construct a Ka-band full-MMIC satellite transponder are described. Two different receiver configurations (an image-rejection type IR type) and a non-image-rejection type (NIR type) have been developed. The configuration of the NIR receiver is same as that of the IR type except for an external filter for image suppression between a low-noise amplifier and a mixer. The IR type is used for receivers incorporating the low-noise amplifier and mixer in one housing. The NIR type is used when the low-noise amplifier is installed separately from the receivers. Total system performance of a Ka-band receiver breadboard model incorporating the MMIC modules is reported. Test results indicate successful performance as a satellite receiver system.<>
